Axial Steady State Forced Response

Axial Steady State Forced Response

This option calculates the axial steady state forced response for a given range of rotor speed due to Steady State Excitation. It will be calculated only when the excitation exists. The excitation amplitude and frequency can be functions of rotor speed.

For forced response analysis, the modal damping can be specified if the direct damping is not readily available. Details on the damping model are explained in the Modal Damping. If modal damping is specified, then the vibratory force caused by the damping, i.e., the second term in the above equation, will not be included.
