Abstract
This paper presents an optimum concept to design passenger-friendly vehicle suspension system with the help of Taguchi approach. A full car suspension is considered as an illustrative example of vehicle model to demonstrate the concept and process of optimization. The experimental have been conducted by varying the stiffness of four shock absorbers (A), damping co-efficient of four shock absorbers (B), stiffness of seat (c) and damping co-efficient of seat (D) is taken as input parameters. 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 using MSC ADAMS. In addition mathematical model using regression model is done for both seat displacement (DS) and settling time (ST). The results show that stiffness of shock absorber and stiffness of seat spring are there most significant parameters which affect the seat displacement, while damping coefficient of. The concept proposed in this paper is applicable to generic cases, where more complex vehicle model and pavement surface condition apply.
