Abstract:
Shock absorber, an example of under damped vibration system is the key element in the suspension system of any automobile vehicles which aim to absorb a maximum amount of kinetic energy and sometimes potential energy. This paper mainly focuses on the measurement of characteristics of shock absorber. The shock absorber is characterized by its instantaneous value of position, velocity, acceleration, force, pressure, temperature etc and various plots among these parameters. For the measurement of listed parameters of the shock absorber a test rig is designed and developed. An experiment on the test rig is carried out at different speeds and loads which lead to the output in terms of sinusoidal waveform on attached oscilloscope. The waveform is used to find out the characteristics at different load-speed combination. The results obtained are used to find out the behavior of shock absorber at different speed and loads.
