Design of Mechanical Vibration Test System Based on Virtual Instrument Technology
With piezoelectric acceleration sensor, charge voltage filter amplifier, data acquisition card, PC and vibration experiment table for hardware development platform, and LABVIEW for software development platform, virtual instrument technology was applied to the design of mechanical vibration test system. This test system mainly consists of data acquisition, time domain analysis, amplitude domain analysis, frequency domain analysis, time-frequency analysis module. Experimental results indicate: The system not only can perform real-time data acquisition of multiple channels signal, waveform display, data storage, signal analysis, playback measurement and output printing etc, but also has good expansibility, high speed, high accuracy and friendly interface. It is suitable for engineering personnel and laboratory use.
