The recent years have witnessed an accelerated invention and innovation in suspension design. This project aims at finding the ideal combination of suspension and steering geometry parameters viz. tire pressure (typ), damping coefficient (cs), spring stiffness (ks), sprung mass (m), camber (cma), toe (toe) and wheel speed (N), so that the Ride Comfort (RC) is increased while maintaining an optimal degree of Road Holding (RH) using Design of Experiments. The high R-sq value of 97.70%, R-sq (pred) value of 91.85% and the R-sq (adj) value of 95.81% for RC and the corresponding values of 97.99%, 92.98% and 96.33% respectively for RH show the high reliability and predictability of the experimental models. The experimental models were then validated by executing the optimized set on the test rig with an average accuracy of 80%.
