Description

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

F=Dv

v=vRvC

where

  • F is force transmitted through the damper.

  • K is damping coefficient, defined by viscous friction.

  • v is relative velocity.

  • vR and vC are absolute velocities of ports 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

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

Nominal values provide a way to specify the expected magnitude of a variable in a model. Using system scaling based on nominal values increases the simulation robustness. Nominal values can come from different sources, one of which is the Nominal Values section in the block dialog box or Property Inspector. For more information, see Modify Nominal Values for a Block Variable.
