research paper on pneumatic shock absorber

A shock absorber is basically a hydraulic damping mechanism to control the vibrations of the spring. It controls the movements of the spring in both directions: when the spring is compressed and when extended, the amount of resistance required in each direction is determined by the type of vehicle, the type of suspension, the location of the damper in the suspension system And the position in which it is mounted. Shock absorbers are a critical product that the character of a car not only by improving the quality of driving but also by operating to control the attitude and stability of the car body.

 For a smooth and comfortable movement the disturbing forces must be eliminated or reduced Considerably using some devices. Shock absorbers are devices that isolate the Vibrations absorbing some disturbing energies. Of the many telescopic types Shocks are widely used that have the drain that oil flow in the cylinder May cause foaming of oil and air. These limit the optimum throughout the flow in The valves. Gas shocks represent an advance on traditional shocks. Gas filled with nitrogen Shock absorbers are the results of years of research and development Flight crash design engineers. They are designed for both vehicles with Provide shock absorbers that would do anything on the market today. Nitro The shock absorbers are high-quality, nitrogen-filled shocks designed and charged with gas Specifically for each vehicle application. The addition of nitrogen under pressure limits.

 The damping mechanism of a damper is viscous damping. Viscosity is the property of a fluid by virtue of which it provides resistance to the movement of the layer over the adjacent in. The main components of a viscous damper are cylinder, piston and viscous fluid. There is a play between the cylinder walls and the piston. More him Plus the velocity of the piston in the viscous fluid and will offer less Viscous damping coefficient value. The basic system is shown below. Damping The force is opposite the direction of the velocity.
