Paper Abstract

The application of virtual instrument (VI) in mechanical shock waveform acquisition and analysis is introduced in this paper. The requirements for the hardware and software design of this virtual instrument are discussed, according to the characters of mechanical shock waveform. Software is the key part of virtual instrument, which is developed under LabWindows/CVI. The software consists of the driver of the data acquisition (DAQ) card, the graphical user interface (GUI), data acquisition control and data processing. Data processing includes tolerance band calibration and check, shock response spectrum (SRS) analysis. The applications of this instrument are demonstrated on the real mechanical shock waveforms and the analysis results.
