## Description

The Sinusoidal Translational Velocity Source block produces sinusoidal translational velocity with a constant offset.

The relative translational velocity between the base and follower interfaces is

`${v}_{FB}={v}_{F}-{v}_{B},$`
where:

• v FB is the relative translational velocity.

• vF is the absolute translational velocity at the follower interface.

• vB is the absolute translational velocity at the base interface.

The defining equation for the sinusoidal translational velocity that the block generates is

`$v={v}_{o}+A*\mathrm{sin}\left(2\pi ft+\phi \right),$`
where:

• v is the output translational velocity.

• vo is the offset translational velocity of the output.

• A is the peak amplitude of the sinusoid.

• f is frequency of the sinusoid in Hz.

• t is time.

• φ is phase shift of the sinusoid.
