Abstract:

With the increasing complex structure of rotating machinery, the failure probability is increasing, so higher requirements for the fault detection technology occurring. The vibration monitoring technology is a main method of fault diagnosis, it judges fault characteristics and position with analysis of the vibration signals of mechanical equipment.Firstly, the principle of vibration monitoring technology and the typical vibration faults are introduced in this article, and using of vibration monitoring technology to illustrate application of vibration monitoring technology in fault diagnosis for rotating machinery.
