摘　　要：针对汽车驱动桥壳变形矫正问题,进行正交试验和数值模拟。以汽车驱动桥壳的材料16Mn为研究对象,通过正交试验优化了火焰矫正时的加热温度、加热面积和加热时间等工艺参数,得到各个因素对矫正效果影响的主次关系。在16Mn低合金钢火焰矫正实验的基础上,采用顺序耦合的方法来模拟火焰矫正,利用ABAQUS的热应力分析计算模块,对驱动桥壳进行求解,得出变形桥壳各点的温度场、应力场及位移分布,为桥壳变形矫正工作提供了有效的工艺参数。On the problem of deformation damage correction in automotive drive axle housing, the or- thogonal tests and numerical simulations were presented. For the 16Mn material of automotive drive axle housing as the research object, through the orthogonal test, the flame straightening of heating tempera- ture, heating area and heating time and other parameters of the optimal process parameters combination were determined; various factors on corrective effects on the primary and secondary relations were ob- tained. Based on orthogonal test of 16Mn low alloy steel, using sequential coupling methods and ABAQUS thermal stress analysis module to simulate the flame straightening. Under the results of analy- sis, the point of the deformation of the axle housing temperature field, stress field and displacement dis- tribution were obtained. Further more, the important reference value for the actual operation to correct the deformation of automotive drive axle housing has been provided.
