Translational Damper

Viscous damper in mechanical translational systems

Mechanical Translational Elements

Description

The Translational Damper block represents an ideal mechanical translational viscous damper, described with the following equations:

F=Dv

v=vRvC

where

FForce transmitted through the damper
DDamping (viscous friction) coefficient
vRelative velocity
vR,vCAbsolute velocities of terminals R and C, respectively

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

Variables

Use the Variables tab in the block dialog box (or the Variables section in the block Property Inspector) to set the priority and initial target values for the block variables prior to simulation. For more information, see Set Priority and Initial Target for Block Variables.

Parameters

Damping coefficient

Damping coefficient, defined by viscous friction. The default value is 100 N/(m/s).

Ports

The block has the following ports:

R

Mechanical translational conserving port associated with the damper rod.

C

Mechanical translational conserving port associated with the damper case.

Introduced in R2007a
