【摘要】：基于齿轮传动动测试验,引入有限单元法多场耦合分析和反求技术,提出了面向工程的复杂齿轮传动摩擦多性态概念,建立了复杂齿轮传动的"计算-试验综合模型".在典型传动工况下,通过试验提取轮齿敏感区域的特征参数(齿根应变),并以此作为齿面摩擦因数反求的输入;借助有限单元法多场耦合分析技术真实模拟相应传动工况下的齿轮传动过程,并提取对应位置的齿根应变;由此建立以摩擦因数为自变量的目标函数,利用隔代映射遗传算法(International projection Genentic Algorithm,IP-GA)的全局快速的搜索能力进行优化,输出在此传动工况下的齿面摩擦因数.相对于传统求解方法而言,该方法将系统建模、理论研究、数值模拟与试验测试相结合,实现了复杂齿轮传动系统齿面摩擦因数的量化计算,求解更趋合理.齿面摩擦的深入研究,对完整构建齿面摩擦特性参数的计算理论体系、探索齿轮摩擦机理、促进减振降噪技术的开发均具有重要的意义.
[Abstract]:Based on the dynamic test of gear transmission, the multi-field coupling analysis and reverse engineering technique of finite element method is introduced, and the concept of tribological polymorphism of complex gear transmission for engineering is put forward, and the "computation-test comprehensive model" of complex gear transmission is established. Under typical transmission conditions, the characteristic parameters (root strain) of the sensitive region of the gear tooth are extracted by experiments, and used as the input of the tooth surface friction coefficient. With the help of the finite element method multi-field coupling analysis technique, the gear transmission process under the corresponding driving condition is simulated, and the tooth root strain of the corresponding position is extracted, and the objective function with friction coefficient as the independent variable is established. The global fast searching ability of projection Genentic algorithm IP-GAA is used to optimize the tooth surface friction coefficient under this driving condition. Compared with the traditional solution method, this method combines system modeling, theoretical research, numerical simulation and test to realize the quantitative calculation of tooth surface friction coefficient of complex gear transmission system, and the solution is more reasonable. The further study of tooth surface friction is of great significance for the complete construction of theoretical system for the calculation of tooth surface friction characteristic parameters, the exploration of gear friction mechanism and the development of vibration and noise reduction technology.
