Description
Block Translational Velocity Source It is a speed source that generates a speed difference at its terminals proportional to the input signal.
The R and C connections are mechanical ports that maintain translational motion. Port S is the signal controlling the source. The relative speed (speed difference) at the source is directly proportional to the signal at the control port S. All the variety of signal sources can be used to create the desired rate change profile.
The positive direction of the block is from port R to port C. This means that the speed is measured as , where — absolute velocities at ports R and C, respectively, and the force passing through the source is negative if it acts from C to R. The power generated by the source is negative if the source supplies power to the R port.
Ports
Input
S — control signal, m/s
scalar
The input port through which the control signal is applied, actuating the source.
R — rod
translational mechanics
A mechanical channel for maintaining translational motion associated with the moving part of the source (rod).
C — case
translational mechanics
A mechanical port for maintaining translational motion connected to the initial control point (body).
