Research on the Lightweight Drive Axle Housing of Electric Farm Management Machine

The paper shows that the drive axle housing of the electric farm management machine not only has the role of carrying and transmitting power, but also plays a supporting role for the main reducer, brake and other components, which needs to meet the requirements of stiffness and strength. Three-dimensional modeling and finite element analysis are used to design the joint, and a reasonable three-dimensional modeling of the drive axle housing is carried out. Aiming at the structural quality of the axle housing, the finite element analysis method is used to reduce the quality of the axle housing. Firstly, the force analysis is carried out according to the maximum vertical force condition of the drive axle housing. Secondly, the static and dynamic characteristics of the axle housing structure are analyzed. Then, with the parameters that have great influence on the quality as the design variables, the quality of the axle housing as the optimization objective, and the maximum static stress and maximum deformation as the constraint conditions, the Latin hypercube experimental design method and genetic optimization algorithm are used to carry out the lightweight design of the axle housing. Finally, through the optimization scheme, the total weight of the axle housing using structural steel is reduced from 169.4kg to 156.83kg, achieving a weight reduction effect of 7.42%, and realizing the lightweight of the axle housing.
