Virtual Instruments Based Approach to Vibration Monitoring, Processing and Analysis

pdf PDF


This paper shows the design procedures of a virtual system (VI) that is based on LabVIEW software with the aid of National Instruments (NI) Data Acquisition Devices (DAQ). The function of the system developed in this paper comprises data acquisition and generation operations. In addition, it also involves the implementation of several signal processing and analysis techniques such as Fast Fourier Transform (FFT) and Infinite Impulse Response (IIR) filters. The application of the proposed VI can be expanded according to the user requirements. For example, it can be used in the area of vibration monitoring, signal processing and analysis. This may include field dynamic balancing or fault detection and diagnosis. In this work, a measurement system, consisting of an integrated circuit piezoelectric (ICP) accelerometer and data acquisition device (DAQ) was prepared and assembled for the experiments. A shaker was used to produce a periodic vibration signal and hence simulates the most common vibration fault signatures experienced by rotating machines. A program in LabVIEW was designed to collect and analyse the simulated vibration signals in both time and frequency domains.
