Ideal velocity source in mechanical translational systems
The Ideal Translational Velocity Source block represents an ideal source of velocity that generates velocity differential at its terminals proportional to the input physical signal. The source is ideal in a sense that it is assumed to be powerful enough to maintain specified velocity regardless of the force exerted on the system.
Connections R and C are mechanical translational conserving ports. Port S is a physical signal port, through which the control signal that drives the source is applied. The relative velocity (velocity differential) across the source is directly proportional to the signal at the control port S. The entire variety of Simulink® signal sources can be used to generate the desired velocity variation profile.
The block positive direction is from port R to port C. This
means that the velocity is measured as
the absolute velocities at ports R and C, respectively, and force
through the source is negative if it is acts from C to R. The power
generated by the source is negative if the source delivers energy
to port R.
The block has the following ports:
Mechanical translational conserving port.
Mechanical translational conserving port associated with the source reference point (case).
Physical signal input port, through which the control signal that drives the source is applied.
