Ideal Translational Velocity Source
Ideal velocity source in mechanical translational systems
Simscape / Foundation Library / Mechanical / Mechanical Sources
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 v = vR – vC, where vR, vC are 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.
S — Control signal, m/s
Physical signal input port, through which the control signal that drives the source is applied.
R — Rod
Mechanical translational conserving port associated with the source moving part (rod).
C — Case
Mechanical translational conserving port associated with the source reference point (case).
