Description
The Shock Absorber block represents a spring-damper system that absorbs vibrations. An internal force acts between ports R and C. This force is the sum of spring stiffness, damping, Coulomb friction, and hard-stop contributions. All force contributions are optional.
The block is a composite of these blocks:
Block | Function | Library |
---|---|---|
Loaded-Contact Translational Friction | Coulomb friction | Simscape / Driveline / Brakes & Detents / Translational |
Translational Damper | Damping | Simscape / Foundation Library / Mechanical / Translational Elements |
Translational Spring | Spring | |
Translational Hard Stop | Hard stop |
Assumptions and Limitations
Setting Hard stop to
Compliant hard stop
or setting Coulomb friction force to a nonzero value enhances model fidelity, but reduces simulation speed. For more information, see Driveline Simulation Performance.
