This paper presents an optimum concept to design passenger-friendly vehicle suspension system with the help of Taguchi Approach. A quarter car suspension systems is used as an illustrative example of vehicle model to demonstrate the concept and process of optimization. The numerical analysis is carried out in MATLAB/Simulink by varying the stiffness of shock absorber, damping co-efficient of shock absorber, stiffness of seat and damping co-efficient of seat. The values of suspension parameters have been obtained by using the Taguchi design of experimental method. The implication of input parameters on seat displacement (DS) and settling time (ST) has been investigated by using analysis of variation. The optimum system parameters are predicted using Taguchi analysis and verified by the confirmation analysis carried out by using MSC ADAMS.

Keywords: Quarter car model, Taguchi Method, Optimization, Vehicle dynamic system
