摘要
运用CATIA建立某型商用车驱动桥壳的实体模型,利用Hypermesh划分网格,参照标准QC-T 533规定的台架试验方法,对桥壳进行弯曲刚度、垂直静强度有限元仿真计算。通过量化分析应力集中、尺寸及表面加工情况等疲劳影响因素,引入疲劳寿命仿真分析。依据QC-T 534规定的评价方法,桥壳上述指标均符合国家标准,仿真结果与试验结果一致。同时指出桥壳存在问题,为下一步优化指明方向。
The geometric model of the driving axle house of a commercial vehicle is established with Catia. Hypermesh is use for mesh generation. According to the bench test method of the standard QC-T 533 ,bend stiffness and static strength are simulated. Influence factors for fa- tigue life, such as stress concentration, size and surface processing, are quantified. Through the simulation analysis, fatigue life is figured out, and reaches the standard according to the evaluation method of QC-T 534. Simulation results are consistent with experiment. Meanwhile, the potential problem is found for the next step of optimization.
