FINITE ELEMENT ANALYSIS AND LIGHTWEIGHT RESEARCH OF AN ELECTRIC VEHICLE DRIVE AXLE HOUSING.

The drive axle housing of an electric truck is an important component to ensure the normal operation of the vehicle. The finite element analysis of drive axle housing is a necessary process in the design of drive axle housing. Through the research on the drive axle housing, the four typical force conditions of full load static condition, emergency braking condition, maximum tractive force condition and maximum lateral force condition are analyzed, and their strength is checked according to the national standard of "QC/T 533-2020 China Commercial Vehicle Drive Axle Assembly", so as to ensure the static strength of the drive axle. Through the modal analysis of the drive axle housing, it is ensured that the drive axle housing will not be damaged due to resonance problems during use. Finally, in the requirements of green environmental protection performance, the drive axle housing lightweight research was carried out on the drive axle housing, and through research optimization, the mass of the drive axle housing was reduced by 16.3%, saving a lot of materials. At the same time, the strength performance of the drive axle was also improved. The results show that the finite element analysis of drive axle housing is an important method to design high-quality drive axle housing. Lightweight research can not only reduce the waste of materials, but also improve the structure of the drive axle and improve its performance. [ABSTRACT FROM AUTHOR]
