摘要
分析考虑齿侧间隙的大型半直驱永磁同步风力发电机齿轮箱行星传动系统的非线性动力学响应。使用集中参数法,建立包含啮合刚度、支承刚度、齿侧间隙、传动误差以及外部载荷激励的动力学模型。应用RungeKutta算法进行求解,分别分析输入转速与齿侧间隙对系统非线性响应特性的影响。结果表明,提高转速会增大各构件的扭转振动角位移,但各频率成分未发生明显改变。此外,在齿轮存在双侧间隙的情况下,随着齿侧间隙的增大,系统的非线性逐步增强,系统冲击状态由无冲击转为单边冲击,响应类型由准周期响应转为混沌。
The nonlinear dynamic response of planetary set of large semi-direct drive permanent magnet synchronous wind turbine gearbox considering backlash was analyzed. The dynamic model with meshing stiffness, support stiffness, backlash, transmission error and external load excitation was established by using 1 parameter method. The Runge- Kutta algorithm was used to solve and the effects of input rotational speed and backlash on the nonlinear dynamic response characteristics of the system were analyzed, respectively. The results reveal that raising the rotational speed will increase the torsional vibration angular displacement of each part, but each frequency component is not significantly changed. In addition, the system with double side backlash exhibits that increasing backlash can enhance gradually the nonlinearity degree of system, makes the impacting state of planetary set change from no impact to single-side impact,and the response type changes from quasi-periodic response to chaos.
