Fault Diagnosis System

This paper introduces an on-line monitoring and fault diagnosis system of Fan based on LABVIEW and Advantech PCI-1711 data acquisition card. Through the FFT spectrum analysis of domain vibration, four conditions corresponding to imbalance, misalignment, friction and oil whirl are tested. The result shows that the system can identify these common faults correctly. The system has the advantages of reliable stability, high accuracy and easy manipulation.

Vibration Signal Analysis

As a universal component connection and power transmission gear box, is widely used in the modern industrial equipment, but also an easy failure parts, has a great influence on the running state of the working performance of the whole machine. This paper first analyzes the gear box fault form and characteristics, the gear box fault diagnosis method based on vibration signal analysis, and analysis of the vibration signal processing method for gear vibration signal analysis in time domain, including parameters, resonance demodulation method and cepstrum analysis method. Then using Visual C + + language and data acquisition card for real-time acquisition of gearbox vibration data software, including parameter setting, data acquisition module, signal real-time display module and data storage module. The data acquisition program is developed, the actual acquisition of gearbox vibration data of gear fault and bearing fault, and analyzed.
