摘要
在Pro/E环境下建立某汽车驱动桥壳3D模型,利用NX Nastran软件,按国家驱动桥壳台架试验的标准,在计算机中采用有限元方法模拟其垂直弯曲静刚性试验、垂直弯曲静强度试验和垂直弯曲疲劳试验。同时将有限元计算结果与试验结果进行了对比,吻合较好。因此用有限元模型模拟台架试验的方法是可行的,能实现在设计阶段对试验结果的预测,有效地降低设计成本,缩短设计周期,产生较好的经济效益。
In the Pro / E environment, the establishment of a 3D model of the automotive drive axle housing, the use of NX Nastran software, bench by country-driven axle housing standards, in the computer simulation using finite element method, the vertical static bending rigidity test, the vertical bending static strength Test and vertical bending fatigue test. The same time, finite element calculation results with the test results were compared in good agreement. Therefore, the finite element model to simulate bench method is feasible and can achieve in the design phase of the test results of the forecasts, effectively reduce design cost and shorten the design cycle, resulting in better economic benefits.
