摘　　要：建立了一个三平行轴齿轮耦合转子系统的有限元模型,利用Matlab软件对其进行了固有特性的分析,通过与成熟有限元分析软件ANSYS的计算结果进行对比,验证了该模型和计算结果的正确性。并在此基础上,分别讨论了齿轮啮合刚度、安装角、螺旋角以及轴承刚度对系统弯-扭-轴-摆耦合固有特性的影响。结果表明,齿轮参数会影响系统耦合新频率,而轴承刚度则会造成系统固有频率的突变以及振型的变化。该研究结果为传动系统的优化设计提供了理论基础。A finite element model of a parallel three-shaft gear-rotor coupling system is established.The natural characteristics are analyzed by the Matlab software,and the model is proved to be validity compared with the calculation results by the ANSYS.Based on the model,the influences of the mesh stiffness,the installation angle,the helix angle and the bearing stiffness on the natural characteristics of the bending-torsional-axial-swing coupling system are analyzed.The results show that gear parameters influence the new frequencies caused by the coupling and the variation of bearing stiffness will lead to the saltation of natural characteristics.It provides a theory basis for the optimization design of a traditional rotor system.
