求英文翻译 基于ANSYS的汽车驱动桥壳优化设计

本设计利用ANSYS软件对某 越野车 驱动桥 桥壳 进行优化。
This is an ANSYS optimum design for driving axle housing of a off-road vehicle.

首先建立驱动桥三维模型，分析驱动桥壳在不同工况下的受力情况，计算出驱动桥壳的最大压力。
Firstly, the author established a three-dimensional model of the driving axle. States of stress in different working conditions were analyzed. Furthermore, the maximum pressure of driving axle was achieved.

然后将三维模型导入ANSYS软件中进行网格划分、自由度添加、压力添加等工作。
And then, the three-dimensional model was imported into ANSYS, with some other manipulations, such as meshing, adding degree of freedom, applying surface loads, etc.

接着对桥壳受力情况进行有限元分析，输出计算结果。
States of stress of driving axle were calculated with the results exported.
最后根据质量最轻的目标进行优化，并使应力分布均匀。
Finally, this paper carried out the optimum design according to the target of minimizing the qualitative properties and homogenizing the distribution of stresses. The
经分析验证，本优化设计符合工程要求。
Confirmatory analysis showed that this
