【摘要】 本文从转子发生碰摩时产生的振动信息特征出发,分析了碰摩产生振动量的机量;确认由于这类故障的振动征兆的不确定性,从而采用模糊数学方法来识别故障的可行性.文章介绍了一种新的碰摩故障模拟试验系统及试验结果,对是否出现碰摩故障、碰摩的程度和碰摩的位置进行了模拟试验与诊断.更多还原

【Abstract】 In view of the vibration characteristic information which a rotor turns out when running into rubs,this thesis analyzes the mechanism of the vibration quantities. Furthermore,feasibilities have been affirmed of using fuzzy mathematics as the fault-diagnostic methods .owing to the uncertainty of vibration signs caused by this kind of faults. In this paper,a new simulating test system of rubbing faults is also introduced,as well as simulating tests and diagnoses are taken to find out possibilities,levels and positions of those rubbing faults.更多还原
