Abstract

The introduction of in-wheel motors increases the unsprung mass of electric vehicles, exacerbates vibrations when the vehicle is subjected to road excitation, and affects ride comfort and stability. The in-wheel suspended electric wheel has become an important technical means to improve the above-mentioned problems of in-wheel motors. This paper conducts a vertical dynamic characteristic analysis of two electric wheel configurations. A 1/4 vehicle model was established based on the Matlab/Simulink platform, and the vibration response characteristics of the two electric wheels under different road excitations were obtained. Experimental tests were performed on the vibration characteristics of the two electric wheels using a swept-sine road excitation. The experimental results were in good agreement with the simulation results, verifying the reliability and accuracy of the simulation model.
