加速度传感器的振动筛螺栓松动故障诊断系统
Fault Diagnosis System for Bolt Loosening in Vibrating Screen Based on Acceleration Sensor
摘要
Abstract
A vibrating screen bolt loosening fault diagnosis system based on acceleration sensors is constructed by combining LABVIEW software and NIUSB-6363 data acquisition card for the GLS10 linear vibrating screen spring fastening bolt loosening fault.The loosening fault of the fixed end of the vibrating screen spring cantile-ver beam was simulated by changing the number of loosening bolts.The results show that when the fixed end of the suspension arm of the vibrating screen is loose,its maximum amplitude significantly decreases to 53％of the original amplitude,which can be used to effectively determine the fault type.When the fault type is the same but with various degrees,the acceleration signal spectra obtained varies,and the difference of amplitude is significant,the fault degree of bolt loosening can be determined based on the threshold of the amplitude.关键词
