摘　　要：近年来齿轮传动机构朝着高速、重载、高效的方向发展,这一趋势对齿轮提出了高稳定性、高可靠性、低噪音等要求。针对该要求提出基于幂函数的齿廓修形方法并完成基于幂函数的齿廓修形齿轮的参数化几何建模。为提高齿轮传动的仿真分析效率和精度,联合运用MATLAB与脚本语言Python在ABAQUS环境下对齿轮传动有限元分析模型进行二次开发,实现齿轮动态啮合分析从建模到后处理的参数化流程。通过实例分析相同转速下修形前后齿轮传动的动态啮合性能,结合理论分析验证了分析流程的准确性与高效性,为齿轮传动的动态设计奠定理论基础、提供可行方法。Recently, gear transmission mechanism develops towards the tendency of high-speed, overloading and efficiency, this tendency puts forward high stability, high reliability, low noise on gears. To meet these design requirements, this article comes up with the method of tooth profile modification gears which are based on power function. Besides, it completes geometrical model building of the gears. In order to improve the efficiency and precision of the gear transmission simulation, it brings in MATLAB and script language Python and conducts a secondary development in the environment of ABAQUS. As a result, it comes true parameterization process from modeling to the post-processing. At last, it analyses dynamic meshing performance of gear transmission before and after modification under the same rotational speed. The accuracy and efficiency of this analytical process is verified by a practical example. Besides, it lays the foundation for dynamic design of gear transmission and provides a feasible method.
