摘要
基于有限元法的基本算理,利用有限元软件,从静态和动态两个方面对齿轮进行接触分析,计算出齿根的最大应力,通过与经验公式计算结果对比,有如下结论:1)基于有限元法的齿轮接触分析是切实可行的计算方法,静态和动态模拟数据均比较合理;2)动态接触计算模型计及了啮合过程中的冲击效应和摩擦的影响,相对于静态算法而言,能更为真实的模拟齿轮啮合的真实状况;3)静态接触模型能准确快速地模拟稳态运行状态下的齿轮强度。齿轮的接触强度的合理分析,对改善齿轮传动性能和提高齿轮设计制造水平有一定的意义。
Based on computational theory of finite element method, contact analysis of gear strength is done by finite element software from two aspects of static and dynamic contact computational models. Compared with the results of experiential formulas, the conclusions are drawn： 1 ） The method based on computational theory of finite element method is feasible, simulation data are reasonable;2）Dynamic contact computational model approaches nearer to realistic work conditions because the shock effect and friction are considered in gear drive; 3 ）Static contact model can simulate quickly and accurately gear strength in steady operation conditions . Exact analyzing gear contact strength can help to improve dynamic performance of gear drive and to upgrade the level of design and manufacture of gear.
