10.4.4 Gyroscopic Example

The following example integrates the motion of the gyroscope model that was presented in Section 10.3. The model uses the GyroMoment function, which was also presented in Section 10.3, to reduce the numerical burden of integrating the motion of the rotor. The angular local coordinate system is used, which requires SolveFree to use a coordinate transformation during the integration.

This loads the Modeler3D package and defines names for each of the body numbers.

Here are the constraints, bodies, and loads for the gyroscope model.

The model is run to prepare the initial conditions for SetFree. Note that the rotor has no angular velocity because it is modeled in the GyroMoment load.
