THE REAR SUSPENSION DESIGN OF THE ELECTRIC VEHICLE HaUI-EV2
Abstract
This article presents the content of studying on the designing of rear suspension of the electric vehicle HaUI-EV2. Based on the giving parameters of the HaUI-EV2’s concept, the springs were designed and simulated by Ansys software to get the equivalent stress and deformation of the leaf springs. After that, the results were analyzed and evaluated under the working conditions. The equivalent stress on the surface along the leaf springs must be satisfied with selected material and ensured the material fatigue. Moreover, the maximum deformation of the any leaf spring is also under the limitation following the kinetics calculating of the rear suspension. The achievement of this study is the major factor to complete the design as well as manufacture of the rear suspension system of electric car HaUI-EV2 in the near future.
