摘要
碰摩是旋转机械常见故障之一,通过对转子碰摩机理的分析,提出了利用量子调控技术对转子碰摩进行自愈监控的方法,建立了转子碰摩量子调控自愈机制,对其实现方法进行了分析和研究.该方法不需要考虑引起碰摩的故障原因,只要外加一种力用来抵消碰摩伴随的故障力就可以消除碰摩故障.对量子碰摩自愈机制、量子初态制备、目标量子测量、碰摩自愈监控系统的设计与实现等进行了分析和研究.结果表明,该方法操作简单,使用方便,能有效预防碰摩发生,特别对早期和轻微碰摩更能收到良好效果,为在线消除转子碰摩提供了一种新途径.
The rotor rub-impact is one of the most common faults in revolving machines.In order to ensure normal operation of the rotor system,a way of fault self-recovery monitoring on the early rotor rub-impact was presented.It was based on the fault mechanism analysis of rotor rub-impact using the quantum regulation technique.The method was not meant to consider any reasons for the rotor rub-impact.As long as a force was exerted to offset the rub-impact fault force,the rotor could be returned to its normal condition.Fault self-recovery mechanisms of rotor rub-impact on quantum regulation,preparation on the initial quantum conditions,measurement of the target quantum,and design of the fault self-recovery monitoring system on rotor rub-impact along with its realization technique were studied.Results show that this method is simple in operation and its usage is convenient.It can effectively prevent occurrence of rotor rub-impact and can obtain a satisfactory effect in early rub-impact.It provides a new way for on-line elimination of rotor rub-impact.
