Translational Velocity Source
Source of velocity in mechanical translational systems.
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

R - rod
`translational mechanics'.
A mechanical channel for conservation of translational motion associated with the moving part of the source (rod).
