2 INTRODUCTION Just about every product consists of multiple parts connected by bolts, screws, pins, or springs to create assemblies. Different kinds of assemblies present different simulation challenges. Common to all of them, however, is the need to simulate the connectors that join assembly components simulation that traditionally took a great deal of analysis knowledge and a lot of time. Dedicated analysts find assemblies difficult and time consuming to analyze, despite their specialized education and experience. For example, to simulate a pin connection that is, a pair of mated cylinders connected by a dowel pin that permits or restricts rotation between the parts, such as might be used for a pair of pliers a professional analyst used to have to model the pin that goes through the hinge cylinder and define the gap contact between the pin and the cylinder surface before starting the actual analysis. He also needed to know what size pin to use. Design engineers, for whom the most important part of the day s work is product design rather than simulation, aren t specialist analysts. They are very busy people who don t have the time to simulate connectors in the traditional way. The concepts behind these virtual connectors are the same as those used by generations of dedicated analysts. What if they don t have to? What if the software they use is smart enough to do the tough parts for them? That s just what COSMOSWorks and COSMOSDesignSTAR can do. The programs contain virtual connectors that make it much easier and faster to analyze assemblies containing pin, spring, bolt and screw connectors. The concepts behind these virtual connectors are the same as those used by generations of dedicated analysts. COSMOS takes no shortcuts in accuracy. It offers a simple interface for the user, calling for straightforward input, while putting many of the tasks formerly performed by analysts into the software providing complex, accurate results. V I R T U A L C O N N E C T O R S no. 1

3 Pin Connectors Some examples of pin connectors include hinges for such products as laptop computers, scissors lifts, pliers, and actuators. An example with which everyone is familiar is a set of pliers (fig 1). A pin goes through the two hands that move to open and close the head of the pliers. In conventional finite element analysis (FEA), a typical approach to simulating the pin behavior includes modeling the pin part in a finite element mesh, followed by the analyst defining contact between the pin and the cylindrical faces of the pliers hands. Most of the time, users want to know the effect of the pin upon the parts adjacent to it or upon the overall assembly, rather than the stress distribution on the pin itself. (fig 1) - Virtual pin connector in COSMOS requires minimal input such as the faces that come in contact with the pin as shown in the plier assembly However, if a design model contains multiple pins such as the scissors lift, the use of contact to define pin behavior becomes resource intensive and sometimes impractical to solve. In addition, it may not provide the information most needed. Most of the time, users want to know the effect of the pin upon the parts adjacent to it or upon the overall assembly, rather than the stress distribution on the pin itself. The virtual pin connector in COSMOS was designed for just such scenarios, and makes analysis faster and easier. With this capability, users can learn the forces and moments acting on the pin, and use the information to determine the size of the pin. V I R T U A L C O N N E C T O R S no. 2

4 Defining the virtual pin connection is very straightforward. For the pliers example, the user first identifies the faces that come into contact with the pin. The virtual pin connector in COSMOS can be used to simulate pins that rotate, slide back and forth, or both rotate and slide (fig.2). Because of that choice, the design engineer needs to select the desired movement. Obviously, in the case of a set of pliers, the user will assume that the faces are free to rotate against the pin. Despite the easy-to-use interface, the software performs the same complex tasks needed to define the FEA simulation of the pin described for traditional analysis. (fig 2) - Pin connector in COSMOS can be used to simulate pins that rotate, slide back and forth, or both rotate and slide as shown in this actuator assembly Despite the easy-to-use interface, the software performs the same complex tasks needed to define the FEA simulation of the pin described for traditional analysis. COSMOS models the pin with a beam element, and connects it to the cylindrical faces of the two parts with bar elements for which the user has specified axial and rotational stiffness (fig 3). The relative axial movement of the faces depends on the axial force that develops in the joint and the specified axial stiffness. Similarly, the relative rotation depends on the moment that develops in the joint and the specified rotational stiffness. If the user wants to model a pure pin connection with free rotation, he can choose the option of no translation, and COSMOS will automatically define axial stiffness so that there is no translation while allowing free rotation. (fig 3) - As shown in the inset, pin behavior is modeled with beam elements. Beam element is connected to all nodes on part1 and part2 with bar elements V I R T U A L C O N N E C T O R S no. 3

5 In addition to simplifying pin modeling, the virtual pin connectors in COSMOS make it easy for novice users of analysis software to work with assemblies connected with pins. Unlike past generations of analysts, they don t have to worry about placement of the beam element, nor about the stiffness to use for bar elements to constrain rotation or translation. If the user were to model the virtual pin connector by himself (his only option if using software other than COSMOS), he would have to define the beam and bar element manually. In the example of the pliers, the design engineer would have to create one beam element and 160 bar elements. Then, if the design should change and cause geometry changes or mesh changes through a number of iterations, the user would have to repeat these steps each time. Moreover, if he should make an error in defining the beam or bar elements, he would find it difficult to isolate the error. As difficult as pin connectors may be to model and analyze traditionally, bolt and screw connectors are much harder to simulate. That s because such simulation has to consider the effects of bolt pre-tension and shear. Bolt Connectors As difficult as pin connectors may be to model and analyze traditionally, bolt and screw connectors are much harder to simulate. That s because such simulation has to consider the effects of bolt pre-tension and shear. COSMOS offers virtual bolt connectors that can handle such analysis issues. Users can also learn axial and shear reactions at the bolt to determine bolt sizing, or whether the clamping force generated by the bolt size and the tightening torque is sufficient to overcome the external loads. Similarly to the pin connectors described above, the software is designed with built-in analysis intelligence, so that design engineers only need to define a few required parameters, and let the program perform the difficult calculations. Users have to define parameters (fig 4), such as: the faces of the flanges that will come in contact with the bolt head; bolt shank; nut (if the connector is a screw, nuts won t be used); bolt diameter; bolt material; and bolt preload. The software can automatically compute the bolt preload if the user supplies the bolt tightening torque as well as a torque coefficient to account for the friction at the bolt threads. (fig 4) - COSMOS requires that users identify a few items such as faces the bolts will contact, a bolt diameter, and material. With this information, COSMOS can compute and give the results required to size the bolt. V I R T U A L C O N N E C T O R S no. 4

6 All these inputs can be defined in a single dialog. After reaching the solution, COSMOS provides these results: axial force, shear force and bending moments acting on the bolt (fig 5). (fig 5) - COSMOS provides the required data such as axial force, shear force and bending moments to size the bolt In the case of a grounded bolt, COSMOS uses a virtual wall option to simulate the presence of a concrete floor, and hence simplifies the analysis model size. COSMOS can also simulate the behavior of a grounded bolt, like the one used in traffic light posts (fig 6), in which the bolts are embedded in concrete pavement. In the case of a grounded bolt, COSMOS uses a virtual wall option to simulate the presence of a concrete floor, and hence simplifies the analysis model size. Virtual bolt connectors don t provide data about the stress distribution on the (fig 6) - Virtual Bolt behavior of the traffic light post is modeled using the grounded bolt connector in COSMOS V I R T U A L C O N N E C T O R S no. 5

7 bolt/nut, but rather the effect of the bolt on the parts adjacent to it, or on the overall assembly. If the stress distribution on the bolt/nut is important, the user can model bolt behavior by including the solid model of the bolt and nuts and then using contact conditions rather than the virtual bolt connector. As in the case of the pin connector, COSMOS models the bolt shank with a beam element (fig 7) that is connected to the contact face between the bolt head and flange with rigid bar elements. The other end of the bolt shank is connected to the contact face between the nut and the flange using another set of rigid bar elements. The software models bolt preload by applying an axial force on the beam. The beam element used here is a tension-only element that resists tension but not compression. If the bolt shank diameter is the same as that of the hole diameter in the flange (that is, a tight fit), then the software models the shear effect by connecting rigid bar elements between the flange hole faces and bolt shank. Virtual bolt connectors don t provide data about the stress distribution on the bolt/nut, but rather the effect of the bolt on the parts adjacent to it, or on the overall assembly. (fig 7) - As shown in the inset, bolt behavior is modeled with beam and bar elements. The beam element should be connected by bar elements to all the nodes on the bolt contact face. The same procedure should be repeated for all nodes on the nut contact face V I R T U A L C O N N E C T O R S no. 6

8 Because of those rigid bars that connect the beam with flange faces, stresses close to the area of the bolt/nut may not be accurate. However, this effect decreases gradually until it practically disappears in regions about one bolt diameter away from the bolt faces. Bolt connectors in real life Force Measurement System (FMS) in California makes thrust stands for testing motor and jet aircraft engines. The stands consist of high-precision machine parts bolted together to create the overall system. Recently, one of FMS s clients asked to see the safety factors of each individual bolt in a thrust stand. To do this type of job in the past, FMS s chief engineer Scott McFarlane would have had to model the bolts as spring elements to obtain the forces, and set up the model with the bolt pre-load a time-consuming set of tasks. There just wasn t an easy feature to say I want the bolt torqued to this value of its preload. Instead, I had to do a lot of tedious data input. But the COSMOS virtual Bolt Connector is simple and easy to use, says McFarlane. It took me three hours to set up my model in COSMOS with the virtual connector, whereas before it would have taken two or three days. It took me three hours to set up my model in COSMOS with the virtual connector, whereas before it would have taken two or three days. Spring Connectors A shock absorber offers a good example of a spring connector (fig 8). If an analyst were to model the spring itself and mesh it, he would require many elements to solve the problem because he would find it necessary to model contact between the helical coils when the spring was compressed. As they compress, the stiffness of the springs increases. To analyze spring connectors with traditional FEA, engineers need to know the amount of force required for compression, and they calculate the stiffness as force per length displacement equals spring stiffness, expressed either in feet per inch or Newtons per millimeter. Although the spring manufacturer provides information about stiffness, the analyst needs to see the spring s behavior in its operating environment. (fig 8) - Virtual spring connector in COSMOS requires users to identify the faces that come in contact with the spring and the spring stiffness to simulate the behavior of a spring. V I R T U A L C O N N E C T O R S no. 7

9 With conventional FEA, the mesh density may vary from one part to another, and the engineer who knows the spring s stiffness needs to count the number of actual nodes in the meshed model, and distribute the stiffness equally among all the nodes on the faces connected by the spring. This task is difficult if the number of nodes on the connecting faces are different. Creating even greater complexity, if one part has a coarser mesh than the other, the stiffness will appear to be higher where the mesh density is higher. The process is very difficult and time-consuming in traditional FEA. COSMOS, however, knows the mesh distribution and thus can compute stiffness automatically and more accurately. The user simply picks the two surfaces, inputs the total spring stiffness, and then clicks OK to mesh and run the problem. The software can also work with pre-load in spring connectors. Pre-load occurs when the natural length of the spring becomes partially compressed as is the case, for example, in a push-down action ballpoint pen spring. Spot Weld Connectors Sheet metal parts, such as the panels in the doors of automobiles, are frequently joined by spot welds (Fig 9). With conventional FEA, the mesh density may vary from one part to another, and the engineer who knows the spring s stiffness needs to count the number of actual nodes in the meshed model, and distribute the stiffness equally among all the nodes on the faces connected by the spring. (fig 9) - Sheet metal parts, such as the panel in the doors of automobiles, are frequently joined by spot weld. V I R T U A L C O N N E C T O R S no. 8

10 COSMOS has recently added a virtual spot weld connector. Like the other connectors described above, the software is designed with built-in intelligence, so that design engineers only need to define a few parameters such as the sheet metal surfaces to be welded, spot weld locations, and the diameter of the spot weld (Fig 10). As it does in other virtual connectors, COSMOS models the spot weld with a beam element and connects it to all nodes within the spot weld diameter region. Innovative features such as virtual connectors make it possible for designers to use design analysis in the early stages of the design process rather than passing the task to expert analysts at a later stage. (fig 10) - Simulating spot weld connection in COSMOS is easy and requires few inputs as shown in this car panel example. Virtual connectors clearly save a great deal of work and time. But probably their most important benefit is that they make it possible for designers to analyze several types of assemblies that they would not have analyzed without the software s built-in intelligence. For expert analysts, virtual connectors help them to be more productive by automating repetitious tasks, and by reducing chances of inaccuracies caused by having to repeat detailed manual definition through many iterations. Innovative features such as virtual connectors make it possible for designers to use design analysis in the early stages of the design process rather than passing the task to expert analysts at a later stage. By having the ability to analyze designs early, manufacturing companies can reduce total development time and cost. V I R T U A L C O N N E C T O R S no. 9
