摘要
建立了大功率核电循环泵行星齿轮箱静力学有限元分析模型,对箱体系统进行静力学分析,得出了箱体组件的应力。通过轴承支撑把传动子系统和结构子系统耦合起来,建立齿轮-转子-轴承-箱体耦合系统动力学模型。利用Lanszos方法进行模态分析,得到箱体系统的固有频率和振型。通过分析传动级齿轮啮合频率,得出传动级齿轮在工作过程中造成了较大的振动,但不会产生共振现象的结论,为大功率核电循环泵行星齿轮箱动态性能的提高和优化奠定基础。
The static FEM analysis models of circulating pump planet gearbox are established,then the static strength of gear box is analyzed, and the stress contours are obtained. A coupling system dynamics model is established by coupling transmission subsystem and structure subsystem with the support of bearing. By using Lanszos method, and the natural frequency and vibration models are obtained. It is proved the fact that transmission stage clutch gear causes large vibration by the analysis of the gear mesh frequency with the result, but it will not cause resonance, which lays a foundation for improvement of dy- namic performance and optimization of the planet gearbox used in large-power nuclear station.
