摘　　要：针对某大型能源装置齿轮传动系统,应用拉格郎日方程,建立了系统的非线性动力学模型,模型中考虑了齿轮副的啮合综合误差、时变啮合刚度以及齿轮的啮合间隙。用数值解法获得了在有间隙非线性时变的情况下系统的动态响应,利用时间历程、相平面、Poincare映射以及Fourier频谱分析了该系统的基本性质,并研究了该装置中时变啮合刚度对动态特性的影响。Applying Lagrange equation,the nonlinear dynamic mathematical model was established for planetary gearing transmission of large-scale energy equipments. The time-varying mesh stiffness ,gear composite errors and gear backlashes were considered. A numerical method was applied to solving the nonlinear system with backlash and time-varying, the fundamental nature of the system is analyzed with time histories ,phase plane plots ,Poincare maps and Fourier spectra. The effects of time-varying mesh stiffness on the dynamic characteristics are also studied.
