Facing the new situation of global energy restructuring, occupying the highland of future industry competition and environmental protection, the major developed countries in the world will develop the electric vehicle industry to the national strategic level, and thus the electric vehicle has become the focus of competition among transnational automobile enterprises.In addition to ensuring the power performance of the vehicle, electric vehicles should also satisfy the safety and comfort of passengers and ensure the integrity of cargo transportation. Therefore, it is necessary to study the ride comfort and handling stability of electric vehicles.In this paper, the whole vehicle model is established by ADAMS/Car software, and the ride comfort simulation analysis is carried out. ADAMS/Car software is used to build the models of front suspension subsystem, power assembly subsystem, body subsystem, rear suspension subsystem, tire subsystem and steering subsystem, and then the models of each subsystem are assembled into the whole vehicle rigid body model. The elastomer model of the control arm is generated by setting MNF file, and the rigid-flexible coupling model of the control arm is established by replacing the rigid model of the control arm with the elastomer model. The ride comfort of the rigid-flexible coupling model is simulated and analyzed. The total weighted magnitude is 116.2646. When the speed of the electric vehicle is 40 km/h, the passenger comfort is quite uncomfortable.
