The CosmosWorks tutorial to analyze the response of a component to an applied load. Finite element analysis is a powerful tool that allows engineers to quickly analyze and refine a design. It can be applied to problems involving vibrations, heat transfer, fluid flow, and many other areas. In this tutorial, we will point out where choices and assumptions are made that could affect the accuracy of the results. If you check the box to the right of the add-in name, then that add-in will be activated whenever SolidWorks is started. Most users will prefer to activate COSMOSWorks only when it is needed for an analysis. Click the analysis tab. From the main menu, select COSMOSWorks: Study. A study defines a specific analysis and its results. A single part file can have multiple studies associated with it. In a static analysis, we assume that that loads are applied slowly. If loads are applied almost instantaneously, then dynamic effects need to be considered. A linear static analysis assumes that the response of the structure is linear – for example, a 20-lb load produces stresses and deflections that are exactly twice that of a 10-lb load. Boundary Conditions: When a component is isolated for analysis, the way in which that component is attached to another must be simulated with boundary conditions. In this case, we have chosen a fixed restraint, which means that every point on the back face of the bracket is prevented from moving in any direction. From the main menu, select COSMOSWorks: Load/Restraint: Pressure. Click on the face around the ½-inch hole as shown here. From the main menu, select COSMOSWorks: Mesh: Create. Move the slider bar toward the right (fine) and click the check mark. Mesh Size: A finer mesh, with more elements, will generally produce more accurate results at the expense of longer processing time.
