摘　　要：35T驱动桥属于载货车大吨位桥,市场上出现轴头环缝焊开裂、本体方变圆过渡段断裂和本体加强筋处开裂等故障,经Abaqus有限元分析,确认故障原因为桥壳强度不足所致。通过刚性和强度的有限元分析、3种路况下的Fe-safe疲劳寿命分析以及加工和成本对比的两种优化方案分析,对桥壳进行了结构改进。通过桥壳总成垂直弯曲刚度台架实验,验证了有限元分析过程可信。通过有限元分析、台架实验和市场反馈,证明了结构改进的有效性,对同类产品具有一定的指导和借鉴意义。The 35T drive axle is a large-tonnage truck axle.In the process of use,there are some faults,such as shaft head ring seam welding crack,body square to round transition section fracture and body reinforce ment crack,which are confirmed by Abaqus finite element analysis to be caused by insufficient strength of axle housing.Through the finite element analysis of rigidity and strength,Fe-safe fatigue life analysis under three road conditions,the analysis of two optimization schemes of machining and cost comparison,the structure of the axle housing is improved.The reliability of finite element analysis process is verified by bench test of axle hous ing assembly vertical bending stiffness.Through finite element analysis,bench test and market feedback,it is proved that the structure improvement is effective,which has certain guiding and reference significance for simi lar products.
