Angular Velocity Source
Source of angular velocity in mechanical rotational systems.
Description
The Angular Velocity Source block represents an angular velocity source that generates a velocity difference at its terminals proportional to the input signal.
Connections R and C represent mechanical rotation conservation ports. The S port is the signal that controls the source. The relative velocity (velocity differential) at the source is directly proportional to the signal at the S control port. The entire variety of signal sources can be used to create the desired velocity variation profile.
The positive direction of the block is from port R to port C. This means that the velocity is measured as , where , are the absolute angular velocities at the R and C ports respectively.
A source is positive if it is directed from R to C. The power generated by the source is negative if the source is energising at port R.
Ports
Input
S - control signal, rad/sec.
scalar
The input port through which the control signal that controls the source is input.
R - rod
`rotational mechanics
The mechanical rotation port is associated with the moving part of the source (the rod).
C is the housing
`rotational mechanics
A port of mechanical rotation associated with a reference point (hull).
