The tutorial uses an Inventor assembly. It demonstrates the process to create, solve and view results using 3D plots to illustrate the various mode shapes and corresponding frequency values.
Manual contacts and selection of advanced meshing settings are included. The first 10 mode shapes are found and the results are explained.
Objectives
- Create a new modal simulation.
- Use Manual Contacts to establish the correct relationship between components.
- Exclude components, or use a Design View Representation to remove components from the simulation.
- Override materials.
- Add constraints.
- Manually add contacts.
- Specify mesh parameters.
- Run the simulation.
- View the results.
Prerequisites
- Complete the Assembly Stress Analysis & Contacts and Mesh Refinement tutorials.
- See the Help topic “Getting Started” for further information.
