摘要
根据联轴节及转子轴系特点建立转子轴系力学模型，对转子轴系在不对中激振力作用下的动态响应进行了计算，分析了计算结果，得出不对中故障典型征兆，充实故障诊断专家系统，以便于该类故障的准确诊断。
According to the characters of the coupling and misalignment rotor, the dynamic model
of multi disc shafts is established, and the dynamic response of the rotor system on the
misalignment excitation is calculated in this paper. With the result of the calculating response, the
characters of misalignment and their effects on the stability of the shafts are introduced. The
characters of misalignment faults have been also summarized to enrich the diagnosed rules of
expert system.
