Angular Velocity Source

Source of angular velocity in mechanical rotational systems.

angular velocity source

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 ωωω , where ω , ω 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).
