Abstract: In commercial models and premium vehicles the damping is varied by sensing the road conditions, driver’s action etc. using ECU’s and damping properties are varied every second. This advanced technology is very costly and complicated for middle class consumers who also need some comfort with low cost. The main issue here is to vary the damping of hydraulic shock absorbers according to the shock to which it is subjected. Thus by sensing the speed of the shock absorber and changing the vibration absorbing capacity of the damper with respect to it will surely be useful. In this project we used a spring valve to sense the speed of the Shock absorber and controlling the valve which is fitted inside the damper. By Variable damping pneumatic shock absorber we can get enough comfort with a simple and cost efficient setup.
