The technology behind RecurDyn has superior calculation efficiency because it is based on a recursive formulation. The core is Multi- Flexible Body Dynamics (MFBD) that combines a multibody dynamics solver and a nonlinear finite element method solver at the integrator level. RecurDyn supports other multidisciplinary CAE technologies such as control system modeling, nonlinear system-level optimization, and CFD analysis. RecurDyn provides the efficiency gains of process automation through a wide variety of application toolkits. Users can create their own custom applications using the bundled ProcessNet environment. Flexible Links Gear Creation (with Contacts) Example: Windshield Wiper Simulation <Recursive Formulation> Motor / Controller B e s t c a l c u l a t i o n e f f i c i e n c y : R e c u r D y n implements a recursive formulation for the equations of motion with relative reference frames. The result is an efficient simulation process where the simulation time scales linearly with the size of the model, known as an Order(N) solution. RecurDyn gains additional performance by using a combined explicit and implicit integrator (hybrid integrator) with frequency-based system damping. Number of Calculations Others Forward <High-Speed Contact Calculation> Easy and Fast: The user can quickly define contacts by simply selecting imported CAD geometry. The latest contact detection algorithms are used to attain fast simulations. Many direct analytical contacts algorithms are available to obtain fast and accurate results when working with standard shapes such as spheres, cylinders, boxes, etc. Supports Many General and Analytical Contact Elements Customized Model Building <Intuitive GUI> Focused on MBD: RecurDyn s graphical user interface (GUI) is intuitive and is designed with a focus on multibody dynamics. The tool icons, dialog boxes, and screen prompts are intuitive and easy to understand. RecurDyn is built with the industry-standard Parasolid solid modeling kernel and does not require the user to learn a general underlying CAD package.

3 RecurDyn Features Multi- Flexible Body Dynamics (MFBD) RecurDyn provides a unique MFBD analysis capability that combines MBD with Finite Element Analysis (FEA) methods in order to simulate moving assemblies of bodies in which some are flexible. The user can determine the detailed dynamic stress and stain within the context of a system-level analysis, including the time-varying inertial forces. There are two types of flexible bodies that are supported with MFBD. The first type of flexibly body (RFlex) is a simplified representation that is based on modal data generated by external FEA software. The RFlex solver: Represents the flexible body as a linear superposition of the modes contained in the RFlex input file. Handles complex meshes efficiently and provides the fastest simulation. The second type of flexible body (FFlex) is unique to RecurDyn and is based upon an imported finite element mesh. All nodal degrees of freedom are retained in the calculations. The FFlex body may undergo nonlinear deformation and can accurately simulate sliding contact. RecurDyn/FFlex: Analyzes the detailed deformation of the mesh-based flexible body in combination with the large, nonlinear motion of the rigid body system. Uses FEA mesh data that is provided by any mesh generation software. MFBD has many advantages because it is developed based on MBD Printer Harness Landing Gear Bike Model Suspension Modeling <Advantages> Both RFlex and FFlex flexible bodies can be used together in the same model. All constraint and force entities can be used with both types of flexible bodies. Many rigid bodies can be included in a model with flexible bodies. The flexible body can be deformed in the initial state of the model. <Differences from Explicit FEM> The simulation process is more efficient because the calculation of rigid body motion is performed separately from the calculation of flexible body deformation. RecurDyn includes the full dynamics of the system by considering the inertial forces that result from system motion. ProcessNet RecurDyn/ProcessNet helps users automate repetitive modeling, simulation, and post-processing tasks. ProcessNet provides standard Microsoft development tools (Visual Studio Tools for Applications (VSTA), within the.net framework) with both the C# and Visual Basic languages and with access to the necessary RecurDyn functions. ProcessNet applications are.dll files that can be easily shared by users within an organization. VSTA(VB.NET, C#).NET Assembly COM Wrapper.NET Framework Professional MTT2D FFlex RFlex Toolkits RecurDyn ProcessNet Architecture ProcessNet Example: Development of a Compressor Design Application Engineering efficiency improves with process a u t o m a t i o n ( t e m p l a t e - b a s e d simulation). An abundant collection of GUI tools can be used within custom dialog boxes in order to allow the user to easily define all needed model data. A ProcessNet application is developed in C# using the standard VSTA environment provided with RecurDyn. User inputs that are specific to a company s design process are used to control automated model creation, analysis, and results processing. The ProcessNet application is run directly from the RecurDyn main window. The application can request data from the user, build the model, run the simulation, or automatically display the output in a prescribed format. Processing may include data processing and the generation of a series of plots with custom formatting.

The interface is complete and convenient. <RecurDyn/Solver> RecurDyn/Solver performs the multibody dynamics simulation for the combination of rigid and flexible bodies, contact, forces, and constraints in the model. The Solver: Develops the equation of motion for a robust analysis Performs fast analysis due to its optimized integrator Productivity is improved because the user can concentrate on developing the product rather than adjusting solution parameters. GUI of RecurDyn <RecurDyn/ProcessNet> RecurDyn/ProcessNet helps users develop customized engineering environments. * RecurDyn/Toolkits are optional. Support of Many General and Analytical Contacts RecurDyn provides many types of contact algorithms. The general contact algorithms work with general surfaces that may be imported from CAD software while the analytical contact models work with certain basic geometric shapes. <General Contact Elements> Solid Contact Circle To Curve Sphere To Surface Cylinder To Surface Curve to Curve (Extended) Surface To Surface <Analytical Contact Elements> Cylinder To/In Cylinder Sphere To/In Sphere Sphere To/In Box Cone To/In Cone Sphere To Arc Revolution Sphere To/In Cylinder Sphere To/In Torus Circle To/In Circle Cam2D/CamLine2D Sphere To Arc Extrude Friction effects are considered (both dynamic and static). The coefficient of friction can be defined with spline data. Smooth contact (using cubic splines) is implemented with the Cam Follower. The wide variety of contact functions makes it simple to define efficient contacts. Special force graphics show the magnitude and direction of the contact force. Smooth contact (using interpolation) is possible in the Curve-to-Curve and Surface-to-Surface Contacts.

5 Interdisciplinary Toolkit RecurDyn Modules FFlex RecurDyn/FFlex (Full Flex) directly analyzes the mesh-based flexible body. Nonlinear dynamic behavior, dynamic stresses, and strains of flexible bodies are computed within RecurDyn by the internal combination of the MBD solver with the FEA Solver. RecurDyn/FFlex: Imports the FE mesh in Nastran (.bdf,.dat) and ANSYS (.cdb,.inp) formats. Supports element types: Beam, Shell (Tria3, Quad4, Shell9), and Solid (Tetra4, Penta6, Hexa8, Solid10, Solid26). Displays stress and strain contours. Includes an edit mode for the FE model (creation of node, adding and editing the material properties, creating element and node groups, etc.). Provides a model extract function which retains the deformed state of the flex body in the new mode. RFlex RecurDyn/RFlex (Reduced Flex) provides mode-based flexible body modeling by using FEA modal analysis outputs. Imports the modal results of eigenvalue (linear dynamics) analysis from various FEA software (NX Nastran, ANSYS, ANSYS DesignSpace, Ideas, and MSC.Nastran). Converts a rigid body into the RFlex body while maintaining the constraints (Flexible Body Swap Function). Calculates and displays displacement, stress, and strain contours. Outputs data in a FEMFAT format for use in fatigue analysis. Linear RecurDyn/Linear performs an eigenvalue analysis on a linearization of the model at a specific configuration. Linear models are often required to study the vibrational characteristics of a mechanical system. Because the model employed by RecurDyn for representing systems of rigid and flexible bodies is nonlinear, RecurDyn/Linear generates a linear approximation of the nonlinear content of any RFlex bodies. The modal content of an RFlex flexible body is included in the linear model of the system. RecurDyn/Linear outputs data that can be used in MATLAB and other controls software. The output is: Eigenvalues and eigenmodes State space Matrices (A, B, C, D) EHD RecurDyn/EHD provides a high-fidelity model of an Elasto HydroDynamic (EHD) bearing system in which a shaft makes contact with a bearing. The model considers the oil film on the bearing surface. RecurDyn/EHD analyzes the pressure, forces, and oil film parameters that result from the dynamic interactions between the rigid body and the flexible bodies of the bearing. Also, RecurDyn/EHD defines the pressure applied to the surface of the flexible body as nodal forces using the MForce concept. It is possible to deform the flexible body due to a dynamic pressure load. RecurDyn/EHD uses either the E-CFD solver of RecurDyn or the algorithm provided by Magna Steyr. CoLink Cam Shaft 7 th Mode Cam Shaft 9 th Mode Cam Shaft 8 th Mode Cam Shaft 10 th Mode RecurDyn/Colink is a control simulator that is integrated in the RecurDyn environment and provides a 2D Block Diagram editor to intuitively design the controller signal flow. Standard controllers as well as hydraulics can easily be modeled. The CoLink library consists of: Various signal library A discrete library to model discrete systems A continuous library to model the linear system as a transfer function An actuator library to define standard electric motors An electric drive library to define Motors, including Drives.

6 RecurDyn Modules AutoDesign AutoDesign is a system-level optimization tool that is tightly integrated into RecurDyn. It consists of three modules: The Design Study module: Allows the user to select from a rich set of DOE techniques and perform a series of simulations in order to understand the performance of a RecurDyn model. The Design Optimization module: Uses the DOE outputs to construct a meta-model of the RecurDyn model and then finds the indicated location in the design space with the optimal performance. From that point additional RecurDyn simulations are performed in order to converge to the optimal design using statistical approximation optimization (SAO) techniques. The Robust Optimization module: Allows for variability in specified model parameters, finds the optimal design point while considering the variability, and reports the quality sigma level of the system performance. The capabilities that are integrated into each module include: DOE methods for Effect Analysis: Extended Plackett-Burman Design, Three-level Orthogonal Array Design, Level- Balanced Descriptive Design, Full Factorial Design DOE methods for Meta-Modeling: Discrete Latin Hypercube Design, Incomplete Small Composite Design-I and -II, Generalized Small Composite Design, Box and Behnken Design, Face-Centered Central Composite Design Meta-Modeling Techniques: Simultaneous Kriging Method, Radial Basis Function Method, Conservative RSM Numerical Optimization Methods: Augmented Lagrange multiplier method, BFGS method, Hestenes-Stiefel method, Variable-order polynomial line search method, Weighted Min-Max Formulation for multi-objectives Communicators Optimum design of the MTT3D system by Autodesign Control RecurDyn/Control Toolkit communicates with control system software in order to facilitate a co-simulation between a controller and a mechanical system modeled in RecurDyn. The toolkit plays an important role since design algorithms of a controller and the corresponding mechanical system ( plant ) should be evaluated simultaneously when simulating a computer-controlled system. The control system can be easily designed by control design application software such as MATLAB/Simulink. Hydraulic RecurDyn/Hydraulic supplies the co-simulation function to interface a RecurDyn mechanical model with hydraulic software in much the same way as RecurDyn/Control interfaces with control system software. Files to interact with various versions of AMESim are provided. Interaction with other software is possible but may require the development of routines to output the information in a form that RecurDyn can read. MeshInterface The RecurDyn/MeshInterface makes it easier to create MFBD models using RecurDyn/FFlex. It automates the mesh data interface process, by allowing the user to select a body in RecurDyn and transfer it to meshing software with a single button click. After the body is meshed in the meshing software, the user can quickly bring the mesh back into RecurDyn with another button click. Special functions provide easy swapping between the rigid and flexible body within the MFBD model. Currently, FEMAP from Siemens PLM Software is supported.

7 RecurDyn Modules STEP/IGES/ACIS CATIA Read/CATIA Write RecurDyn provides a set of interfaces to import geometry from various CAD software and/or to export geometry from RecurDyn to the CAD software. Application Toolkits Chain The RecurDyn/Chain toolkit automates the process of defining a chain system and supports standard chain entities such as sprockets, rollers (idlers), guide rails and lateral guards. Roller chains and silent chains can be modeled and analyzed. The chain links are connected by a single pin bushing with flexible characteristics that can be adjusted. Contacts between chain links and the chain system bodies such as sprocket, roller, guide rail and lateral guard are automatically defined. Contact characteristics can be modified. Chain links of a chain system are created by automatically duplicating an initial pair of chain links (inner and outer) that are generated. The toolkit includes special enhancements to the solver for faster simulation Timing Chain system The Belt Toolkit has two assembly methods for defining the belt system. The Segment Assembly method defines a series of rigid belt segments that are connected with bushing, similar to the Chain or Track toolkits. The Element Assembly method defines finite elements (either a series of beams for a narrow belt or a shell mesh for a wide flat belt). The RecurDyn/FFlex module is required to use the Element Assembly method. Belt Types: Flat Belt, Timing Belt, V-Belt, Ribbed V-Belt. Friction forces can be calculated by the Stick-Slip method. The Belt Toolkit supports belt-specific connectors and sensors. The toolkit includes special enhancements to the solver for Belt system faster simulation. Belt The RecurDyn/Belt Toolkit is used to model belt and pulley systems of various types and configurations. Typical applications of the Belt Toolkit include: An engine accessory drive belt system consisting of a ribbed V-belt, ribbed V-pulley, and roller. A continuously variable transmission (CVT) system consisting of a rollers, flanges, and a V-belt. A timing belt mechanism consisting of timing pulleys and a timing belt. Valve The RecurDyn/Valve toolkit consists of a system builder and special functions such as Auto Positioning, Flex Wizard, MMS3D Import and Sphere-in-Arc of Revolution Contact. After setting up the global data, you can easily create valve train components using the system builder. The valve train components are connected by bearings, contacts, or bushings. Valve Types: Direct Type, Rocker Arm (Center- Pivot) Type, Swing Arm (End-Pivot) Type, Push Rod Type Cam shaft Types: Rigid, Torisional, Torisional+Bending, Beam, FEM Direct Type Valve System RecurDyn/Valve enables the user to change all parts from rigid to flexible easily, including the definition of flexible contact. The toolkit features an automatic positioning function.

8 RecurDyn Modules Piston The RecurDyn/Piston Toolkit is a special environment that can be used for models with only one piston and one cylinder. In the Piston Toolkit a boundary condition (which may be defined by experimental data) is used to define the circular movement of the lower pivot of the connecting rod with respect to the engine block. An analytic formula defines the lubrication between reciprocal components such as in the radial bearing and sliding bearing. MMS The design of high-performance engines should consider the floating of valve springs at high engine speeds due to mass effects. The RecurDyn Multi Mass Spring (MMS) Toolkit offers four kinds of MMS springs: Type A: One dimensional spring model considering a collision between coils Type B: Nonlinear spring model powered by BMW AG Type C: Two dimensional pitch spring model with SAKAI algorithm from YAMAHA. Type D: Three dimensional nonlinear spring model with flexible beams. Automatic definition for the contact model between coils. Contact between an inner and outer spring can be modeled. Gear The RecurDyn/Gear Toolkit provides the capability to define a variety of gear geometries and gear (contact) force elements, and to assemble a gear pair with proper engagement. Gear geometries such as spur, helical, QFB and scissors gear can be created from the standard ISO parameters and also using imported CAD geometry. The tooth profile can be represented by multiple arcs or lines. The effects of backlash on system behavior can be evaluated. Gear Types: Spur, Helical, Bevel, Worm, Scissiors, Internal (Spur, Helical) RecurDyn/Gear automates design for the gear tooth, using an involute curve. Users have the choice of contacts (2D, 3D, 3D Contact R [Solid]). The toolkit has specialized solver functionality for faster simulation of the gear system. Crank The RecurDyn/Crank Toolkit is an engine simulation module that consists of a system builder, geometric entities, and connecting elements. The user can create a crank system easily using the system builder. Geometric entities such as an engine block, crankshaft, connecting rod, piston pin, piston, flywheel, torsional damper, balancing shaft, and equivalent drive train (EDT) can be created. Geometric entities are connected using elements such as bearings, engine mounts, linear connectors, gas forces, and Balancing Screw Couplers. After setting up the global data the user can create the crank system components using one of two methods. One method is the System Builder where the user can create components by selecting the geometric entities and connecting the elements the user needs to create. The other is the Manual Builder where the user creates components by clicking the individual component icons in the Crank toolkit. Crank : Crank system having 6 cylinders

9 RecurDyn Modules Bearing The RecurDyn/Bearing Toolkit may define either a ball or a roller bearing. Ball and roller bearings consist of an inner ring, balls or rollers, an outer ring and an outer body (case). The segments of an outer ring are connected with beam forces to describe a quasi-flexible body (QFB). All necessary geometry is automatically created from the users inputs. The effect of clearances in the bearing on system behavior can be evaluated. Ball Bearing Roller Bearing HAT The RecurDyn/Hydraulic Auto Tensioner (HAT) Toolkit helps the user efficiently build a hydraulic auto chain tensioner model. Since the HAT toolkit automates the tedious model generation processes, it improves the efficiency of the simulation process and gives the user time to review and optimize important design parameters. The HAT toolkit automates the creation of the bodies, the translational joints, the spring forces, the contact forces, and the hydraulic forces. A HAT model is created in a standard RecurDyn subsystem to reduce model complexity. All standard RecurDyn capabilities are available in the HAT subsystem. MTT2D The RecurDyn/Media Transport Toolkit 2D (MTT2D) helps users efficiently create and simulate sophisticated models of flexible media being transported by a mechanical system in a 2D environment. The MTT2D toolkit automates tedious model generation processes and automates the generation of relevant output plots. The basic modeling of a flexible sheet which can represent paper, film, or other flat sheets, is possible. Templates for sheet-guiding entities such as idealized rollers and guides are also included. RecurDyn/MTT2D: Automates the creation of guides from 2D CAD data (STEP, IGES). Automates the definition of contact between the media and the rollers and guides along the media path. Enables Soft-nip model. Creates the curled and folding shape in the initial state. Includes Nodal Forces which can be used to model air resistance, absorption forces, and electrostatic forces.

MTT2D: Transportation system for the second-dimension flexible media MTT3D The RecurDyn/Media Transport Toolkit 3D (MTT3D) helps users efficiently create and simulate sophisticated models of flexible media being transported by a mechanical system in a 3D environment. MTT3D improves the efficiency of the simulation process and gives the user the time to review and optimize important design parameters because it automates tedious model generation processes and the generation of relevant output plots. MTT3D automates the basic modeling of a flexible sheet as a 3D FEA mesh (shell elements), which can represent paper, film or other flat sheets. Templates for sheet-guiding entities such as idealized rollers and guides are also included. Imported 3D geometry can be used to define a guide surface.

10 RecurDyn Modules Track_LM Track_HM Low mobility (LM) tracked vehicles are typically construction equipment where the track shoes are defined through a profiling method. High mobility (HM) tracked vehicles are typically military vehicles where the track shoes are defined as a combination of a steel frame and track pads. The RecurDyn/Track toolkits support the definitions of sprockets, roadwheels, idlers, and an initial track shoe. The track is automatically defined by replicating the initial track shoe along the path indicated. The track links are connected by two bushings at each junction. Track_HM entities: Track Shoe (Single, Double, InnerPin), Sprocket, Roadwheel (Single, Double) Track_LM entities: Link, Sprocket, Roller (Single, Double, Center, Flat), Roller Guide A GUI is provided for sprocket tooth definition and the sprocket teeth are replicated automatically Contacts between track links and the track system bodies are automatically defined and contact characteristics can be modified by the user. Terrain can be extracted from a library of terrains, created in RecurDyn/Modeler or imported using standard profile files or imported geometry. Contact between the track and the terrain can be defined by stiffness, damping, and friction or by a soil model based on Bekker s theory. The toolkit uses specialized solver functionality for faster simulation of the track system.
