| 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. |
