Problem DescriptionO-rings have many industrial applications where they act as seals to prevent the passage of gas or fluid from one space into another. In this example, you simulate sealing a cylindrical vacuum chamber, which is assembled with a top plate, an O-ring, and a bottom plate with a groove. You apply a force to the top plate to push the O-ring into the groove in the bottom plate. As the top plate pushes the O-ring into the groove, the O-ring flattens vertically but expands laterally, causing it to contact the groove walls. Since the assembly and the applied load are axisymmetric, you create a 1-degree cut-section of the assembly to reduce the analysis time of the simulation. ![]()
The top and bottom plates are made of AISI-304 steel, while the O-ring is made of a custom rubber material. You use the Mooney-Rivlin model to represent the O-ring's hyperelastic material behavior. The assembly and initial simulation setup were created in SOLIDWORKS. You save the assembly to the 3DEXPERIENCE platform and complete the simulation using 3DEXPERIENCE simulation apps. WorkflowThe workflow diagram below provides an overview of the example. The diagram shows the apps that you use as you perform the steps in sequence. Clicking a number in the diagram opens its corresponding step in the example. ![]()
Complete the workflow steps in the order in which they are listed. Deviation from the instructions associated with each step might cause model or scenario errors, which might prevent convergence of the simulation. |
