1 ARLA Simulation in Cooperation with ITI (SimulationX - Page 1) SimulationX The Powerful Simulation Software Package for the Future Introduction SimulationX is a standard software for valuation of the interaction of all components of technical systems. It is the universal CAE tool for modeling, simulation and analyzing of physical effects with ready-to-use model libraries for 1D mechanics, 3D multibody systems, power transmission, hydraulics, pneumatics, thermodynamics, electrics, electrical drives, magnetics as well as controls postprocessing included. SimulationX is the trend-setter in physical system simulation. The model libraries including validated model components are being developed in close cooperation with numerous industrial partners and research institutes. The program with its customer-oriented modules and editions, numerous functionalities and interfaces fulfils the requirements for users application tasks. SimulationX is a new modeling and simulation tool launched in September The development was motivated by the growing needs to analyze modern technical, mechatronic and heterogeneous systems. The tool is unique in terms of library integration, modeling comfort and flexibility. It has been developed as a CAE application with an up-to-date user frontend. Benefits The application of SimulationX ensures a cost-efficient, target-oriented and efficient development of system solutions. Thereby all development partners contribute their core competence in a development environment they are familiar with. This provides a significant competitive advantage. With SimulationX a tool became available, which enables engineering service providers, as well as engineers in the technical departments of medium and large enterprises, to develop, virtually test and analyze components and systems of arbitrary complexity. Your major benefits are: Using SimulationX the engineers from different disciplines can transfer subtasks into component or system models using their familiar and efficient development methods. SimulationX models the interaction of components from a multitude of domains including their mutual interaction and feedback. This significantly distinguishes SimulationX from any other kind of CAE software (FEM, CFD, MBS). SimulationX as the common modeling and simulation platform in system development creates a base for mutual understanding of all concerned parties.

2 ARLA Simulation in Cooperation with ITI (SimulationX - Page 2) The dynamic system behavior of modern and complex machines and plants is manageable, controllable, and interpretable throughout the whole development process as well as during error analysis. Development and simulation tasks, which cover several components and subsystems and include pre- as well as post-processing are solved faster using SimulationX. The application of SimulationX reduces development costs and minimizes expenses for cost-intensive prototype testing on the complete system as well as design changes. The observability of arbitrary system quantities in the model, including those, which are hardly or not at all accessible in measurements, leads to a considerably deeper understanding of the overall systems. The access to validated and transparent SimulationX models and their parameters in system development ensures a high certainty of conclusions concerning the realizability of desired performance parameters of a design or plant as well as concerning the evaluation of proposed solutions. SimulationX considerably boosts system integration. Different physical properties (e.g., mechanical, thermal, electrical) and different sub-systems (drive, machine, process) are described independently of each other, but are simulated, analyzed, and optimized in their interactions. A target-oriented expansion and modification of virtual sub-systems allows to break completely new ground. SimulationX considerably improves product quality. The consideration of a growing number of system variants based on virtual models which are close to reality opens up the possibility of a holistic examination, comparison, and evaluation of new solutions. Practical Use Developing simulation models for technical components and systems implies the inclusion of the different physical effects, ranging from mechanics to hydraulics, thermics, pneumatics, magnetics, or even electronics, but also the consideration of the involved controls. SimulationX is used as a system simulator by the practical engineer in all industrial branches. The general concept is to provide one homogeneous platform for modeling and simulation of mechatronic systems without any need for co-simulation, mathematically described inputs or code export/import. ARLA & ITI in cooperation The most obvious advantage of SimulationX is its graphical user interface with flexible and intuitive working methods. Dialogs and windows are wellstructured, comfortable and easy to understand, units are available for each parameter or variable, algebraic and/or logical expressions can be used for any parameter. Model objects can be grouped together easily to form new model types and elements. Additional ports can be assigned among other things to any standard element.

3 ARLA Simulation in Cooperation with ITI (SimulationX - Page 3) Physical Domains SimulationX supports to use the most convenient way of modeling in each of the engineering domains - signal blocks in the control domain, circuit diagrams in the electronic, magnetic and fluid domains, functional sketches in 1D mechanics, and 3D geometrical structures with visualization and animation in 3D mechanics. The all-domain ITI modeling philosophy opens up new application fields for real system simulation and analysis including: Linear and Rotary Mechanics Multibodies Hydraulics Pneumatics Controls Electronics Magnetics All modeling domains can be used simultaneously within one model. Alternatively, the user may describe its models (or components of it) in the Modelica language. In this way, models can be created very fast and intuitively from the existing standard model libraries. Special nonstandard components can be implemented in Modelica.

11 ARLA Simulation in Cooperation with ITI (SimulationX - Page 11) Model Examples More than 300 models are available to support your daily work with SimulationX. Starting with basic and simplified applications to real and complex systems, they create for example solvable 3D models or demonstrate basic concepts for time-continuous controllers. There is a Model Pool in the internet which allows you to download different model examples simply and safely for your use. Libraries Mechanics 1D Content Model Ball is a one-mass oscillator modeled by elements of the library Linear Mechanics. Basic model examples as EndStop, RigidFriction, NonlinearCoupling, etc. can be used for mechanical effects. There are many OneMassOscillator samples modeled by elements of the library Linear Mechanics. Fast consideration of nonlinear stiffness, various forces or excitations is possible by changing of model structure and parameters. Mechanics 3D Bodies, joints and forces are most efficiently defined when positioning MBS connections in joint positions as shown in sample Pendulum. Moreover this leads to numerically more adventageous system descriptions. The sample FourBarLinkage demonstrates how to create solvable 3D models avoiding redundant constraints in closed kinematic chains (e.g. mechanisms). The model SliderCrank3D gives an idea, how to obtain its consistent initial state by releasing initial velocities in connections. This task is a necessity in any simulation run. Signal Blocks A signal generator is used in the model Sweep for a non-linear frequency domain analysis of a mechanical system with backslash. Basic concepts for time-continuous controllers are demonstrated in the models pidcontrolloop, pidantiresetwindup, and HysteresisCompensation and for time-discrete controllers in the models DeadBeatController, DiscretePI. The phase locked loop example PLL employs mainly Special Signal Blocks. Electro- Mechanical The models show the usage of the different motor types.

The example SimpleSolenoid belongs to next level in modelling including some iron material. The magnetic properties of the iron material can be set up in various ways. In the model ConstAirGap the iron properties are provided by a data base while in the model IronMaterialUserDefined they are given by a user defined characteristic.

The control of mixture mass composition is explained in MixingExample. Power Transmission ElasticCouplingDriveTrain and ElasticCouplingSimple show powertrains with elastic couplings as damper elements. A lot of powertrains need clutches to connect and to disconnect drive and work machine while operation. In PressWithDiscClutch the motor accelerates the flywheel up to its nominal speed. Then the clutch closes and the press works. AsynchronousMotor is a model of a test stand for asynchronous motors. The motor runs up without load und will be decelerated up to standstill. The combustion engine element simulates oscillating crank torques which have to be damped as shown in the model CombustionEngineWithTorqueDamper. Furthermore this model shows how to build a nonlinear coupling. At least the models PlotterWith2Servos and SpeedControlledServoDriveTrain show samples of using the servo elements. Typically servos are speed controlled, but there are uses for position controlled systems. PlotterWith2Servos includes two servos with position controls and subordinated speed controls. 2arySpurGearWithFixedBearing shows a gearbox model using two gear elements. The model simulates parameter excitation and gives an example how to model elastic shaft bearings. In BoxerEngine you ll see a model using two crank elements.
