| 摘 要： | 通过对齿轮旋翼传动系统进行理论分析，在运转的条件下进行实验测定和在线识别，指出由于旋翼的非线性耦合作用，使得带有旋翼的齿轮传动系统具有不同于其它齿轮系统的特有特性，即动态特性随转速的不同而发生变化，并得到了其变化规律。

| Abstract: | A gear transmission system with a helicopter rotor was experimentally investigated and on-line identified during its operation,and the results were compared with its theoretical analysis.It is found that the gear transmission system with a rotor differs from other gear transmission system by such natural characteristics,that its dynamic characteristics change with it's rotational speed.It's changing law has also been obtained,which provides basis for the dynamic modeling analysis and the dynamic design of the system and an effective analytical approach of the gear transmission system. |
