Description

Block Translational Damper It is an ideal mechanical translational viscous damper described by the following equations:



where

  • — the force transmitted through the damper;

  • — coefficient of damping (viscous friction);

  • — relative velocity;

  • — the absolute speeds of ports R and C, respectively.

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