摘要：

采用ABAQUS进行了后桥减速器壳体轴承座裂解起裂模拟，通过J积分和裂解槽尖端Z向拉应力探究了激光预制裂解槽深度对裂解载荷和变形的影响规律，结果表明：裂解槽在轴承座厚度中间面位置面对应节点的J积分在不同槽深的整个模拟加载过程中保持最大，裂解起裂在此位置发生；参考连杆裂解预估壳体轴承座裂解裂载荷603 kN时，槽深大于0.7 mm情况下轴承座厚度中间面位置面对应节点的模拟最大拉应力超过抗拉强度，裂解起裂发生，起裂时壳体轴承座仅仅在裂解槽起裂位置局部微小区域进入塑性状态；根据J积分判据确定了不同裂解槽深度的模拟裂解载荷，绘制和拟合了裂解槽深度和载荷曲线，603 kN对应槽深为0.797 mm。并对激光预制1.0 mm深度的裂解槽进行裂解实验，实际裂解载荷和模拟裂解载荷误差为4.30%，试件内径变化值为0.16~0.24 mm，小于轴承孔裂解加工允许塑性变形（≤0.4 mm）。综合模拟分析结果并结合实际生产，采用激光加工后桥减速器壳体轴承座裂解槽深度参数范围为0.8～1.0 mm。

Abstract:

Abaqus software is used to simulate the cracking of the bearing seat of the rear axle reducer housing. The influence of the depth of the laser prefabricated cracking groove on the cracking load and deformation is investigated through J-integral and Z-direction tensile stress at the tip of the cracking groove. The results show that the J-integral of the corresponding node at the middle wall thickness of the bearing seat remains at its maximum during the entire simulated loading process， and cracking occurs at this position. Referring to the cracking of the connecting rod， when the estimated cracking load of the shell bearing seat is 603 kN and the groove depth is greater than 0.7 mm， the simulated maximum tensile stress of the corresponding node at the middle position of the bearing seat wall thickness exceeds the tensile strength， and cracking occurs. When cracking occurs， the bearing seat housing only enters a plastic state in a small local area at the cracking position of the cracking groove； Based on the J-integral criterion， the simulated cracking load for different cracking groove depths is determined， and the cracking groove depth and load curve are plotted and fitted. The corresponding groove depth for 603 kN is 0.797 mm. And a cracking experiment is conducted on a laser prefabricated cracking groove of 1.0mm depth. The actual cracking load and simulated cracking load have an error of 4.30%， and the change in the inner diameter of the specimen is 0.16~0.24 mm， which is less than the allowable plastic deformation （≤ 0.4 mm） for bearing hole cracking processing. Based on the comprehensive simulation analysis results and combined with actual production， the depth parameter range of the cracking groove in the bearing seat of the rear axle reducer housing processed by laser is 0.8 mm to 1.0 mm.

Key words: cracking processing, bearing seat of the rear axle reducer housing, cracking groove, numerical simulation, cracking load
