摘要
文中以航空发动机附件的直齿圆柱齿轮传动系统为研究对象,利用集中质量法建立了系统的耦合振动模型,在模型中考虑了时变啮合刚度、静态传递误差和齿侧间隙等非线性因素。利用Runge-Kutta数值计算方法对系统的非线性动力学方程进行求解,得到了系统的动态仿真结果,结果显示系统具有很强的非线性,并结合时间历程、相平面和poincaré截面图对响应进行了分析比较。讨论了内部激励频率对系统动态特性的影响,分析了系统随着内部激励频率的变化表现出的不同运动状态。
This thesis focuses on the two-staged cylindrical spur-gear transmission system in accessory drive casing of aero-engine. By using Lumped-mass Method, a coupling vibrant model that includes time-variant meshing stiffness, transmission errors and backlashes et al is established. Employing Runge -Kutta integration method, the governed nonlinear dynamic equations are solved. The steady state responses show the strong -nonlinear behavior of the transmission system. Based on time history, phase plane plot and Po...
