Optimal Roll Center Height of Front McPherson Suspension System for a Conceptual Class A Vehicle

In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle is studied first and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for analysis of vehicle dynamic behaviour in different positions of suspension roll center, then optimization process has been done using ADAMS/Insight. Results show significant effects of roll center location on body roll angle, body roll rate and steering response. Also, the contradiction between body roll and steering response can be observed
