| 摘 要： | 采用整体传递矩阵法计算某型拖拉机发动机的固有频率特性,计算中考虑发动机机匣的影响,将发动机转化成多转子相互耦合的系统,导出各向同性耦合单元的传递矩阵,并给出了算例。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,为开发拖拉机发动机整机固有频率特通用软件提供了有效的方法。

| Abstract: | The natural frequency characteristics are calculated by the whole transfer matrix for tractor motor coupling multi-rotors system.The transfer matrix of isotropic coupling element is derived and some numerical examples are given in the paper.The method prevents the difficulties in developing a common program of the traditional sub-system transfer matrix method,provided a valid method for developing common program. |
