Sinusoidal Torque Source | Engee Documentation

Description

Unit Sinusoidal Torque Source is a constant offset sinusoidal torque source. A positive torque value creates a torque directed from port B to port F.

The defining equation for sinusoidal torque:

where

- is the output torque;
- is the output bias torque;
- peak amplitude of the sinusoid;
- frequency of the sinusoid in Hz;
- time;
- phase shift of the sinusoid.
