WebThat said, for any given point on a damping curve for a typical passenger car shock, you might see a c value of something like 1000-10000N/m/s. Super hard to say, really, since shocks are pretty non-linear, but as a not-very-helpful value it's about 0.5 to 0.8 depending on the application. Pneumatic and hydraulic shock absorbers are 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 (see below). 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 hydrauli… Webforced vibrations in the oil volume and damper structure, sticking effects on the valve flaps, valve reactions, and oil foaming and cavitation.
