建立桨轴发动机整机动力响应的分析方法 ,用传递矩阵法建立发动机机匣、主燃气发生器转子、自由涡轮转子的综合动力学方程 ,并对耦合方程进行求解。此方法有效地考虑了主燃气发生器转子系统与自由涡轮转子系统的耦合效应。可分析主燃气发生器转子与自由涡轮转子系统的临界转速和不平衡响应 ,估计机匣系统的不平衡响应 The method to analyze the dynamic response of the whole propeller shaft engine is established, and the comprehensive dynamic equations of the engine casing, the main gas generator rotor and the free turbine rotor are established by the transfer matrix method, and the coupling equation is solved. This method effectively considers the coupling effect between the main gas generator rotor system and the free turbine rotor system. The critical speed and unbalance responses of the main gas generator rotor and the free turbine rotor system can be analyzed to estimate the receiver system imbalance response
