【摘要】 介绍了用整体传递矩阵法计算航空发动机多转子相互耦合系统的固有频率特性。该方法克服了传统子结构传递矩阵法不易编制通用计算软件的缺点。同时，用有限元法对支承机匣刚度进行了计算。并以某航空发动机转子系统为例验证了方法的有效性。更多还原

【Abstract】 The natural frequency characteristics are analysed by the whole Transfer Matrix method for turboengine coupling multi-rotors system. The method prevents the difficulties in developing a com- mon program of the traditional sub-system transfer matrix method. Furthermore, the supporting shell stiffness is calculated by the Finite Element method. The rotor system of an aeroengine is taken as an example to verify the effectiveness of the stated method.更多还原
