Impact on the Vehicle Ride Comfort Caused by the Changes of Unsprung Mass
Abstract
Compared with traditional vehicles, the unsprung mass of new energy vehicles which are driven by the hub motor is obviously increased. In order to analyze the impact on the vehicle ride comfort caused by the changes of unsprung mass, a vehicle model is built for the ride comfort simulation by using ADAMS/ Car. Then the road test is carried out to verify the accuracy of the vehicle model. Finally, in order to reduce the adverse effects caused by the changes of unsprung mass, the parameters of suspension are optimized by using Adams/Insight.
