多工况下牵引车驱动桥壳多目标优化设计
Multi-objective optimal design of drive axle housing of tractor under multiple load cases
摘要
Abstract
Dealing with the strength-based and lightweight design of a tractor drive axle housing with a double-rear tandem suspension,this paper performed a topology optimization under multiple load cases to get a better material distribution in high stress areas;Then Kriging surrogate models between variables and responses were established,with weight and stress being the multiple objectives.The results of this paper offers a range of reference designs in axle housing optimization,for example,the optimal design reduces weight of the axle housing shell by 6.5％,the maximum stresses under braking and traction conditions by about 10％,and the fatigue life of welds is increased by 23.0％,which can effectively meet the needs of lightweight design and fatigue life of the axle housing.关键词
