Matlab的转子故障振动信号分析

摘要

随着机械行业的日益发展,转子等旋转机械的故障日渐趋多,转子的故障诊断技术受到越来越多的重视,并在世界范围内取得了长足的进步。作为大型机器中不可或缺的部件,有着举足轻重的作用,但,,,,。对发电机及其转子进行状态监测和信号分析,,

转子故障类型主要有四种:转子不平衡、、转子的故障类型及机理Matlab软件,在Matlab软件中建立起转子故障图形程序,利用Matlab中的程序对仿真信号及故障数据进行分析,包括信号的时域图、频域图以及轴心轨迹图,

ANALYSIS OF ROTOR FAULT VIBRATION SIGNAL BASED ON Matlab

Abstract

With the development of the machinery industry, the rotor and other rotating machinery are becoming more and more common. Rotor fault diagnosis technology has been paid more and more attention, and has made great progress in the world. As an indispensable part of the large machine, although it has a pivotal role, it comes with own shortcom
