| 摘 要： | 螺栓联接是转子的一种重要联接形式,螺栓预紧力的大小对转子结构的动力学特性有很大影响。首先根据转子螺栓联接结构的工作范围,确定合理的螺栓预紧力的数值。然后,通过Compbell图方法分析螺栓预紧力对转子临界转速数值的影响。最终通过瞬态动力学的方法验证了Compbell图方法计算的正确性。

| Abstract: | Bolt connection is an important connection form of rotor structure, and the value of bolt preten- sion has great effects on rotor dynamics. Firstly, the reasonable bolt pretension is determined based on the rotor working range. Then Compbell diagram method is employed to analyze the effect on critical speed. Finally, the correctness of the Compbell diagram method is verified by transient dynamics. |
