Description
Block Angular Velocity Source It is an angular velocity source that generates a velocity difference at its terminals proportional to the input signal.
Connections R and C are mechanical ports for maintaining rotation. Port S is the signal controlling the source. The relative speed (differential speed) 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 angular velocities at ports R and C, respectively.
A source is positive if it is directed from R to C. The power generated by the source is negative if the source supplies power to the R port.
Ports
Input
S — control signal, rad/s
scalar
The input port through which the control signal is applied, controlling the source.
R — rod
rotational mechanics
The mechanical rotation port is connected to the moving part of the source (rod).
C — case
rotational mechanics
The mechanical rotation port connected to the reference point (body).
