Sinusoidal Translational Velocity Source

Source of sinusoidal translational velocity.

sinusoidal translational velocity source

Description

The Sinusoidal Translational Velocity Source unit is a constant offset sinusoidal translational velocity source.

Relative translational velocity between stator and rotor:

where

  • - is the relative translational velocity;

  • - is the absolute translational velocity at the junction with the rotor;

  • - absolute translational velocity at the interface with the stator.

Defining equation for sinusoidal translational velocity:

where

  • - is the output translational speed;

  • - is the displaced output translational velocity;

  • - peak amplitude of the sinusoid;

  • - frequency of the sinusoid in Hz;

  • - time;

  • - phase shift of the sinusoid.
