Abstract

Due to the defect of traditional test instrument,such as high cost and poor flexibility,a vibration test system based on the LabVIEW,a graphic programming language,is designed,according to the principles and demands of vibration test.This system is composed of two parts: the hardware is to transform and input the vibration signal into computer through sensor,modulating circuit and DAC card.The software uses LabVIEW 2011 to accomplish the function of data acquisition,signal generation and signal processing.Meanwhile,the software of this instrument was introducd specifically in this paper.
