Investigation of Variable Damping Shock Absorber Performance of Automotives in Shock Prone Areas

Abstract

Shock absorbers allow the use of springs and hydraulic shock absorbers to absorb and dissipate vibration. A shock absorber consists of a helical spring and a damper. A spring has its spring constant and a damper has a damping coefficient. In this project a variable shock absorber model is developed by varying the spring constant which is achieved by using helical spring with variable pitch in coils and varying coil diameter and a variable damper. Research involved improving the shock absorber by using variable spring and a variable damper to come up with variable shock absorber model which adjusts depending on the shock. The governing equations were solved; Analysis of various parameters such as damping coefficient, spring constant and damper fluid temperature are considered and their effect on damping. The results obtained are discussed and presented graphically
