Torsional Steady State Forced Response

Torsional Steady State Forced Response

This option calculates the torsional steady state forced response for a given range of rotor speed due to Steady State Excitation. The Steady state Forced Response Analysis will be performed only when the steady state excitation exists. The excitation amplitude and frequency can be functions of rotor speed. Details are explained in the Modeling-Data Editor.

The element vibratory torque is calculated by:

If modal damping is specified, then the vibratory torque caused by the damping, i.e., the second term in the above equation, will not be included.
