Sinusoidal Force Source | Engee Documentation

Description

The Sinusoidal Force Source block represents a constant displacement sinusoidal force source. A positive force value generates a force acting from port B to port F.

The defining equation for the sinusoidal force:

where

- output force;
- is the displacement of the output force;
- amplitude of the sinusoid;
- frequency of the sinusoid in Hz;
- time;
- phase shift of the sinusoid.
