In order to increase the stability and movement safety of electric vehicles (EV) under various operation conditions, the battery mass distribution on the EV floor and its load dynamics are concerned in this study. An EV dynamic model with the different battery mass distributions on the EV floor is established and investigated. The EV dynamic equations are then solved via the Simulink model built on Matlab software. The acceleration responses at centre of gravity of the EV and wheel dynamics are two objective functions for evaluating the EV movement safety. The research results show that the optimal position of the battery mass distribution on the EV floor and the ratio between the battery mass and the EV body mass should be reached with from 1.2 to 1.4 m and ≤ 0.6, and the EV's velocity should be from 20 to 35 m/s, therefore, the EV movement safety is remarkably improved.

In order to study the influence of heavy truck dynamic parameters on the vehicle’s ride comfort under the random road excitation, the weighted RMS (root-mean-square) acceleration responses of the vertical driver’s seat and cab pitch angle are chosen as objective function, a dynamic model of the vehicle with 10 degrees of freedom is established to simulate and analyze the results. The influence of different parameters of all the suspension systems of the vehicle, such as the stiffness and damping of the suspensions of the seat, cab, vehicle, and wheel, on the vertical driver’s seat and cab pitch angle are respectively analyzed. The study results show that the influence of the stiffness and damping parameters in the suspension systems on the vehicle ride comfort is very obvious. The vehicle’s ride comfort changes worse with the increase of the suspension stiffness and the reduction of the suspension damping, and vice versa. The study proposes an optimal range of the stiffness and damping parameters for the optimal design and control of the vehicle suspension systems, concurrently, the study can also provide a theoretical basis for the suspension system designed for heavy trucks.
