Implementation of Taguchi Method for Robust Suspension Design

In this paper, Taguchi method of robust optimization has been adapted along with Design of Experiments methodology and ANOVA to reduce the variability in the Ride comfort of a vehicle with respect to sprung mass of vehicle. It aims to find a combination of tyre pressure, spring stiffness and damping coefficient which gives a constant and targeted comfort value with reduced variance. The analysis suggests that the tyre pressure of 35psi with the spring stiffness of 26,000 N/m and damper of damping coefficient 418 N-s/m, maximize the SN ratio and reduce the deviation in RC due to mass, hence resulting into a robust design.
