【Abstract】 Based on LabVIEW software development platform,a non- stationary process for rolling bearing fault diagnosis and performance evaluation system is established,and the hardware and software of this system are designed. The system uses NI9234 data acquisition card,collecting and analysing vibration and instantaneous angular velocity signal on the variable conditions of rolling bearing. This system integrates multi- channels data acquisition,test stand control,database storage and analysis based on this paper algorithms.更多还原
