Modeling Rigid Bodies

Application ID: 10566

In many structural dynamics applications, some components are stiff compared to the supporting structure. Such a stiff part will only contribute to the dynamic properties of the structure through its mass and moment of inertia. It is then possible to reduce the model size significantly by treating it as a rigid body. In this example the eigenfrequency of an assembly is computed where one of the parts can be considered as a rigid domain.

This model is included as an example in the following products:
