| in the palette | on the schematic |
The block is designed to simulate a two-way translatory stopper. The stopper includes two stops limiting the relative linear position of the bodies connected to the block. Mechanical interaction with stops is simulated by viscoelastic forces. The stiffness and damping of the stops is set in the block properties.
The relative position and relative velocity are calculated by the formulas:
where:
- s – relative position, m
- sC and sR – positions of bodies at ports "C" and "R", respectively, m
- v – relative speed, m/s
- vC and vR – speeds at ports "C" and "R", respectively, m/s
