Translational Damper (Advanced)
Linear damping in mechanical translational systems.
Description
Unit Translational Damper (Advanced) represents a linear mechanical progressive viscous dampener. From the start of the simulation, the block uses a nominal damping coefficient. The linear mechanical progressive viscous damper is described by the following equations:
where
-
- is the force transmitted through the damper;
-
- damping coefficient (viscous friction);
-
- relative velocity;
-
- absolute velocities of the 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.
