“…32 shows that the bending rigidity (Mohseni Kabir et al, 2017) of the frame without stiffeners is K B1 = 548.78 N mm −1 , and that the bending rigidity of the frame with stiffeners is K B2 = 1007.01 N mm −1 , indicating an increase of 83.50 %. When the chassis structure is under a bending load, the displacement should not be larger than 1 mm (Dzerkelis et al, 2012). After deducting the weight of the hub motor and front wheel, the force at the center of gravity of the full vehicle is 890.53 N, and the force induces a 0.88 mm displacement at the center of gravity of the structure.…”

Abstract. This paper discusses a systematic vehicle design process in which light weight is taken as the vehicle design objective, and the designed frame is analyzed in detail. The load condition of a vehicle under different circumstances is calculated according to the distances from the front and rear wheels to the centroid position. The stress on the components in the condition is analyzed by finite element analysis, the steering geometry of the vehicle is analyzed, and the vehicle's turning angle and radius are designed. The displacement of the vehicle under a load is calculated by rigidity analysis to determine the stability of the vehicle in motion. The experimental modal analysis of the real frame and the finite element method are verified mutually for the electric vehicle body-in-white (BIW) manufacturing process to determine the consistency of model formation and the real frame. In terms of the circuit design, we used no-fuse switches and fuses to provide overcurrent protection for the main power supply, and the chip is combined with an optically coupled circuit and current sensor, which is driven by a restriction controller for protection. Moreover, a solid-state relay (SSR) is used for current protection and for controlling the forward/reverse rotation of the motor.

“…Dzerkelis et al [11] in their paper discussed upon the deformations of the body affected by static forces and found that the results obtained by numerical methods and the results obtained by modeling differ almost twice. Such a difference of the obtained results may be caused by certain preconditions accepted upon striving to simplify the construction.…”
