NTE240型矿用车驱动桥壳结构强度与模态分析

摘要

To prove that the drive axle housing of NTE240 electric wheel mining dump truck is reasonably designed, a three-dimensional model is established for drive axle housing by using Pro/E software, and the model is imported to Ansys Workbench to build finite element model of axle housing. In addition, Ansys Workbench is used for structural static analysis and modal finite element analysis of drive axle housing. The analysis results reveal that the axle housing has sufficient static strength and rigidity, and is highly resistant to vibration, which can provide reference for the structural optimization design of axle housing.%为验证NTE240型电动轮矿用自卸车驱动桥壳设计的合理性,利用Pro/E软件建立驱动桥壳的三维模型,导入Ansys Workbench建立桥壳的有限元模型,并通过Ansys Workbench进行驱动桥壳的结构静力学分析和模态有限元分析.分析结果显示,该桥壳具有足够的静强度和刚度,并具有足够的抗振性.上述分析结果可以为桥壳的结构优化设计提供参考依据.
