| 摘 要： | 基于有限元法对圆柱接触和齿轮接触进行静力学分析，为了能够更精确、更有效率地分析出接触应力的分布结果，考虑了划分网格的类型和表面切向应力对接触应力的影响。在Solidworks中对圆柱和齿轮进行三维建模，将建好的三维模型以合适的格式导入到ANSYS Workbench中进行网格划分，并按要求施加合理的约束处理，使用其基于有限元理论的求解器进行计算求解，得到模型在特定载荷作用下的应力分布图。采用赫兹接触理论值和齿轮接触应力理论值，分别对有限元分析后的圆柱接触和齿轮接触的结果进行对比，得出分析结果的误差和精确性。分析结果表明，划分网格的类型会影响分析效率，表面切向应力会影响接触分析应力的分布，这使得接触分析的结果更加精确，同时也提高了相关工作人员的效率。

Static Analysis of Three-dimensional Gear Contact Based on Finite Element Analysis |
| |
| Abstract: | Static analysis of cylindrical contact and gear contact was carried out mainly based on finite element method.In order to analyze distribution of contact stress more accurately and efficiently，influence of meshwork type and tangential stress on contact stress was mainly considered.Three-dimensional modeling of cylinders and gears was carried out in Solidworks，and then the built three-dimensional model was imported into ANSYS Workbench in an appropriate format for mesh division，and reasonable constraint processing was applied according to requirements，and its solver based on finite element theory was used for calculation and solution.Stress distribution diagram of model under specific load was obtained.Using Hertz contact theory value and gear contact stress theory value，finite element analysis of cylindrical contact and gear contact results were compared，error and accuracy of analysis results were obtained.Analysis results showed that，meshwork type would affect analysis efficiency，and surface tangential stress would affect stress distribution in contact analysis，which made contact analysis results more accurate and improved efficiency of related workers. |
