摘要
建立了静子与转子部分的数学模型，提出了借实测的安装节动刚度，计算各主轴承到安装节的传递函数和转子系统的动力响应，进而预计发动机整机稳态动力响应的方法。附有一双转子航空发动机计算实例。
A mathematical model of rotor and stator is given. A calculation method is established to calculate the dynamic response of engines mounting points by using the measured dynamic stiffness of the mounting points. Both the dynamic response of rotor stator system and the transfer function between main supports and mounting points can be calculated simultaneously. Finally, a certain type of double spool aeroengine is taken as an example.
