Ride comfort performance evaluations on electric vehicle conversion via simulations

Abstract

The paper presents a simulation study on the ride comfort performance of a passenger vehicle which is expected to be converted into an electric vehicle. The studies involved evaluations of vehicle's ride comfort, performance before and after the conversion being made using a validated simulation model. The studies used a validated 7 degrees of freedom of vehicle ride comfort model of the passenger vehicle that is expected to be converted into an electric vehicle. The model was used to evaluate the vehicle ride comfort performance when it's being converted into an electric vehicle. It is done by varying the weight distribution load at the front and rear axles. The vehicle's vertical acceleration, displacement, pitch rate and pitch angle are the responses observed in this study. It was found that the EV conversion's ride comfort was not significantly affected from the modifications.
