摘要
齿轮箱体作为齿轮箱的基础零部件,为其内部的齿轮提供了结构支持与保护等作用,需要保证其自身的稳定性与可靠性。利用SolidWorks建立齿轮箱体三维模型,将模型导入ANYSYS Workbench中对箱体进行静力学分析以及模态分析。静力学分析结果表明齿轮箱的最大应力为25.191 Mpa,位于齿轮箱输入轴于输出轴的孔中;最小应力为2.2864e−2 Mpa,位于齿轮箱的顶部。模态分析得出,齿轮箱体的各阶固有频率和振型,随着阶数的增大,其变形量变化的数值较小,为齿轮箱体的结构优化设计提出进一步的理论依据。
As the basic component of a gearbox,the gearbox provides structural support and protection for the internal gears,and it is necessary to ensure its own stability and reliability.Build a 3D model of the gear box using SolidWorks,and import the model into ANSYS Workbench to perform static and modal analysis on the box.The static analysis results show that the maximum stress of the gearbox is 25.191 Mpa,located in the hole between the input shaft and the output shaft of the gearbox;The minimum stress is 2.2864e−2 Mpa,located at the top of the gearbox.Modal analysis reveals the natural frequencies and modes of each order of the gear box.As the order increases,the numerical changes in deformation are relatively small,providing further theoretical basis for the structural optimization design of the gear box.
