Aiming at the problem of frequent failures of key components of electromechanical equipment,a vibration test system based on LabVIEW diagnostic platform is designed through the design and development of software and hardware structure of vibration acquisition module,programming of lower and upper computer control,with the method of fault vibration signal acquisition,processing and analysis,and the goal of improving the accuracy of fault diagnosis. Through system interconnection,vibration test experiments are conducted,and vibration data are displayed in four channels in real time to observe the vibration signal amplitude and phase and reflect the equipment fault characteristics. Through the comparison and analysis with MATLAB software data processing,the developed system has a higher degree of operational simplicity and visualization,and is more feasible and practical in vibration testing,which can be applied to the industrial field processing process to realize online monitoring and fault analysis of vibration signals of electromechanical equipment.
