摘要
考虑输入和输出端横向振动与系统扭转振动的耦合作用,建立大型船用齿轮箱三级齿轮传动系统横扭耦合动力学分析模型,利用基于能量的Lagrance法建立传动系统耦合动力学方程。采用Matlab软件计算了在时变啮合刚度和误差激励下的某大型船用齿轮传动系统固有特性和动态响应分析,得出系统动态良好,不存在共振现象,在工作负载下系统处于概周期振动的结论。
Taking the coupling interaction between transverse vibration and torsional vibration of input and output end into account, a transverse-torsional coupling dynamic analysis model of triple geared drive system of large marine gearbox is established and dynamical coupling equations of transmission system is built according to energy-based Lagrance Law. The natural characteristic and dynamic response of this drive system are analyzed using MATLAB software. The result shows that there＇s no resonance phenomenon in the system, it has a good dynamic performance and operates almost periodically under the current operating load.
