以某人字齿轮传动系统为研究对象,提出了一套齿轮系统级动力学建模和仿真分析的方法。基于有限元节点法建立考虑刚性转子-轴-轴承-齿轮啮合作用的动力学模型,分析系统的共振转速,与实验结果进行对比,验证了有限元节点法模型的可靠性和局限性;基于节点法齿轮啮合作用建模方法建立三维有限元模态分析模型,分析了齿轮系统的固有频率和振型;最后,结合模态分析和响应分析,与实验结果进行对比,判断实验共振原因,实现共振定位,为实验减振避振提供了方向。
A herringbone gear transmission system is taken as the research object. A method of gear system-level modeling and simulation analysis is proposed. Based on the finite element node method,a dynamic model considering rigid rotor-shaft-bearing and the meshing of gears is established. Then the resonance speed of the system is analyzed and the result is compared with the experimental data to verify the reliability and limitations of the finite element node model. Then a 3D finite element model used for natural frequency calculation and vibration mode analysis is established. The modeling of gear meshing is used in finite element node method. Finally,combined with the modal analysis and response analysis,the theoretical analysis is compared with the experimental data. And the cause of experimental resonance is determined and resonance localization is realized,which provides direction for decreasing the vibration amplitude and avoiding the vibration.
