中文摘要：

利用有限元分析软件ABAQUS,对比分析了实际工况下不同淬火温度和淬硬层厚度的汽车半轴法兰盘的应力分布规律。结果表明,法兰盘内圆角表面残余应力随淬硬层的厚度增大而减小,而最大主应力增大,说明大的淬硬层厚度并不好;高的淬火温度有助于减小内圆角处的最大主应力。这能为法兰盘的淬火工艺及结构优化设计奠定基础。

英文摘要：

Stress distribution law of automobile semi-axle flange with different quenching temperature and quenched harden layer thickness under the actual working condition were compared and analyzed by using the finite element analysis software ABAQUS. The results show that, the residual stress distribution in flange inner fillet surface decreases with the quenched harden layer thickness increasing, while the maximum principal stress increases, which indicates that a larger quenched harden layer thickness is not good. Higher quenching temperature contributes to reduce the maximum principal stress distribution at the inner fillet. This can lay the foundation for the quenching process and structural optimization design of flange plate.
