发布时间:2018-11-23 08:18
【摘要】:通过MATLA-APDL混合建模法,建立了精确的齿轮模型;利用实验提取关键摩擦特性参数,借助有限元软件的数值模拟功能和隔代映射遗传算法,对不同润滑状况下齿面摩擦因数进行反求分析,较好地解决了复杂曲面摩擦因数难于求解的问题。相对于传统求解方法而言,该方法能较好地模拟齿面摩擦的真实情况,求解结果更具合理性。对齿面摩擦因数的合理反求,可为齿轮的数值模拟提供一定参考,并对改善齿轮传动性能和提高齿轮设计制造水平亦有一定的意义。
[Abstract]:The accurate gear model is established by MATLA-APDL hybrid modeling method. The key friction characteristic parameters are extracted by experiments, and the tooth surface friction coefficient under different lubrication conditions is analyzed by using the numerical simulation function of finite element software and the genetic algorithm of alternate mapping. The problem that the friction coefficient of complex surface is difficult to solve is well solved. Compared with the traditional method, this method can simulate the real situation of tooth surface friction, and the result is more reasonable. The reasonable reverse calculation of the tooth surface friction coefficient can provide a certain reference for the numerical simulation of the gear, and also has certain significance for improving the gear transmission performance and improving the gear design and manufacturing level.
