As the core component,rotor system may run abnormally,have the failures of unbalance,bearing damage and incorret alignment.

作为它的核心部件，转子系统运行过程中可能出现不平衡、不对中、轴承损坏等故障。

The dynamic equation of the transient response in a cracked rotor system was modelled, the numerical simulation solutions of the uncracked rotor and the cracked rotor were obtained.

摘要基于建立的裂纹转子瞬态回应动力学模型，得到了有无裂纹转子的数值仿真解。
