摘要为研究多级定轴齿轮传动系统的动态特性优化方法，以大型矿用齿轮箱为对象，利用广义有限元思想建立包含齿轮设计参数与系统布局参数的宏观参数动力学模型，采用Newmark-β时域积分法对额定转速工况下的动力学方程进行求解，在此基础上建立优化模型，在优化过程中实现了一个基于势能法的可优化的动态方程中的时变啮合刚度计算程序，同时提出了包含系统动态特性与体积优化在内的多目标优化方法，并与单一目标的优化方法进行比较。研究结果可为矿用齿轮传动系统的宏观参数设计提供理论参考。

Abstract：In order to study the optimization method of dynamic characteristics of multi-stage fixed shaft gear transmission system, a macro parametric dynamic model including gear design parameters and system layout parameters is established by using generalized finite element method with a large mining gearbox as the object. Newmark-β time domain integration method is used to solve the dynamic equations under rated speed conditions. On this basis, an optimization model is established. During the optimization process, a time varying meshing stiffness calculation program in the dynamic equations that can be optimized based on the potential energy method is realized. At the same time, a multi-objective optimization method including system dynamic characteristics and volume optimization is proposed, and compared with the single objective optimization method. The research results can provide a theoretical reference for the macro parameter design of mine gear transmission system.

Key words： Multi-objective optimization;Parametric dynamic model Layout parameter Dynamic performance;Macro parameters
