Force Source
A source of mechanical energy that generates a force proportional to the input signal.
Description
The Force Source unit represents a source of mechanical energy that generates a force proportional to the input signal.
Connections R and C represent mechanical ports that maintain translational motion. The S port is the signal that controls the source. You can use a variety of signal sources to create the desired force profile. A positive signal on port S generates a force acting from C to R. The force generated by the source is directly proportional to the signal on the S control port.
The positive direction of the block is from port C to port R. This means that the force is positive if it acts in the direction from C to R. The relative velocity is defined as , where are the absolute velocities at ports R and C respectively, and it is negative if the velocity at port R is greater than that at port C. The power generated by the source is negative if the source supplies power to port R.
Ports
Input
S - control signal, H
scalar
The input port through which the control signal that drives the source is input.
R - rod
translational mechanics
A mechanical port of translational motion associated with a moving part of the source (rod).
C - housing
`translational mechanics'.
A mechanical port of progressive motion associated with a reference reference point (housing).
