Shock Absorber:
A shock absorber is a mechanical device designed to smooth out or
damp shock impulse, and convert kinetic energy to another form of
energy. It is used in conjunction with cushions and springs. An
automobile shock absorber contains spring-loaded check valves and
orifices to control the flow of oil through an internal piston.
One design consideration, when designing or choosing a shock
absorber, is where that energy will go. In most shock absorbers,
energy is converted to heat inside the viscous fluid. In hydraulic
cylinders, the hydraulic fluid heats up, while in air cylinders,
the hot air is usually exhausted to the atmosphere. In other types
of shock absorbers, such as electromagnetic types, the dissipated
energy can be stored and used later. Shock absorbers help cushion
vehicles on uneven roads.
