摘　　要：为了研究多种非线性因素共同作用下的风电机组行星齿轮箱的动力学特性和混沌性,建立了包含太阳轮浮动、时变啮合刚度、综合啮合误差、齿侧间隙等非线性因素的平移-扭转耦合动力学模型。以某1.5 MW风机的传动链为研究对象,对实际运行中不可避免的行星轮系太阳轮浮动进行了建模,在此基础上建立更加完善的系统动力学模型。通过数值解法对系统动态响应进行求解,绘制了系统的分岔图、相轨线、Poincare截面和功率谱以分析风机传动链随激励频率变化的分岔混沌特性。结果表明,太阳轮浮动会显著影响系统的动态响应和混沌性。研究结果对风机传动链的优化设计、生产制造具有一定的指导意义。In order to study the dynamic characteristics and chaos of the planetary gearbox of wind turbine under the combined action of various nonlinear factors,a translation-torsion coupling dynamic model including nonlinear factors such as sun gear floating,time-varying meshing stiffness,comprehensive meshing error and tooth side clearance is established.Taking the transmission chain of a 1.5 MW wind turbine as the research object,the inevitable floating of the planetary gear train sun gear in actual operation is modeled,and a more perfect system dynamics model is established on this basis.The dynamic response of the system is solved by numerical method,and the bifurcation diagram,phase trajectory,Poincare section and power spectrum of the system are drawn to analyze the bifurcation and chaos characteristics of the fan drive chain with the change of excitation frequency.The results show that the floating of the sun gear will significantly affect the dynamic response and chaos of the system.The research results have certain guiding significance for the optimal design and manufacturing of the fan drive chain.
