摘　　要：研究了复杂多轴齿轮传动系统整体传递矩阵方法及在直升机动力传动系统扭转振动分析中的应用.首先说明了直升机传动系统传递矩阵方法力学模型,推导了传动系统中典型齿轮副啮合传递矩阵、并车级和行星级齿轮啮合传递矩阵,说明了这种具有多种齿轮副啮合的复杂多轴系统整体传递矩阵模型组集方法,最后用这种方法进行了典型直升机动力传动系统扭转振动特性分析,讨论了这种直升机动力系统振动特性的特点.The multi-shaft transfer matrix method （TMM） with differential gear mesh and the torsional vibration characteristics of the helicopter power system have been investigated. Firstly, the analytical model for the helicopter power system was built by the transfer matrix method. Next, the ＇mesh transfer matrix＇ for the two shaft and three shaft gear pair, and the planetary gear pair were established using transfer matrix method. Then the torsional vibration characteristics of the helicopter power transmission system were obtained using the multi-shaft transfer matrix method. Lastly, the natural frequency and vibration mode properties was discussed.
