تغيير ممتص الصدمات

A damper is a system for limiting or suppressing oscillation of an object or of an object to be isolated from vibration energy dissipation. Free and forced vibrations correspond to the movement of a mass on a spring. During oscillation, there is kinetic energy and potential energy alternately one damper dissipates some of the kinetic energy, usually by heat. Many physical principles can be used: losses of fluid, friction, hysteretic behavior,
