| 摘 要： | 本文简要介绍汽轮发电机组中的碰摩故障,并用模糊集间的距离和贴近度的概念分析和计算了单盘模拟转子和实物转子的振动响应。结果表明,贴近度与碰磨力的大小成反比,相对的和绝对的汉明距离,欧几里德距离与碰磨力成正比。

| Abstract: | This paper describes the rubbing faults of turbine-generator set and then presents calculation and analyais of frequency response on simulated rotor with a disc and real rotor using degree approximation and distance concepts of fuzzy sets.The degree approximation is in direct proportion to rubbing force.The Hamming and Euclid disiance is in inverse proportion to rubbing force. |
