摘要
采用传递矩阵法计算转子－机匣系统的临界转速、不平衡响应及初始弯曲响应，计算转子－机匣系统临界转速及稳态响应时的位能与位能分配，提出了借助转子－机匣的位能分配判断各阶临界转速的分析方法，并研究了机匣对系统振动特性的影响。
The transfer matrix method is adopted in the paper to calculate the critical speeds, the unbalance response and the initial curve resoponse of the rotor case system. The elastic energy distributions for stable responses of the system at the critical speeds are obtained. A method is presented to determine the behavior of the critical speeds by making use of the energy distribution between the rotor and the case. And influence of the case on vibration behaviors of the system is studied.[ZK)〗
