Rotational Damper - Simulate viscous damper in mechanical rotational systems

Library

Mechanical Rotational Elements

Description

The Rotational Damper block represents an ideal mechanical rotational viscous damper described with the following equations:

where

TTorque transmitted through the spring
DDamping (viscous friction) coefficient
ωRelative angular velocity
ωRCAbsolute angular velocities of terminals R and C, respectively

The block positive direction is from port R to port C. This means that the torque is positive if it acts in the direction from R to C.

Dialog Box and Parameters

Damping coefficient

Damping coefficient, defined by viscose friction. The default value is 0.001 N*m/(rad/s).

Ports

The block has the following ports:

R

Mechanical rotational conserving port.

C

Mechanical rotational conserving port.
