OPTIMIZATION OF SHOCK ABSORBER PARAMETERS BY USING DOE AND VALIDATION BY MATLAB SOFTWARE

Abstract: Shock absorber is very important term in automobile industries. They are used for the driving comfort and driving safety. This paper presents performance characteristics of the shock absorbers under real conditions. Dynamic behaviours of the absorber are studied by computer simulation and experimental testing and are validated with MATLAB results. The road disturbance is generated in the model by giving speed brakes fixed on drum which is rotated by using motor. In this paper study and analysis of single DOF spring-mass-damper system (Hero Splendor Rear Shock Absorber) and plotted its dynamic characteristics curve for different values of spring stiffness for different oils.

Keywords: Shock Absorber, MINITAB, MATLAB, Optimization-Fuzzy Logic.
