Translational Velocity Source

Source of velocity in mechanical translational systems.

translational velocity source

Description

The Translational Velocity Source block represents a velocity source that generates a velocity difference on its pins proportional to the input signal.

Connections R and C represent mechanical ports that maintain translational motion. The S port is the signal controlling the source. The relative velocity (velocity difference) at the source is directly proportional to the signal at the S control port. The entire variety of signal sources can be used to create the desired velocity profile.

The positive direction of the block is from port R to port C. This means that the velocity is measured as , where are the absolute velocities at ports R and C respectively, and the power through the source is negative when acting from C to R. The power generated by the source is negative if the source is energising at port R.

Ports

Input

S - control signal, m/s
scalar

The input port through which the control signal that drives the source is input.

R - rod
`translational mechanics'.

A mechanical channel for conservation of translational motion associated with the moving part of the source (rod).

C - body
`translational mechanics'.

A mechanical port of conservation of translational motion associated with an initial reference point (hull).
