Abstract: Virtual instrument technique was used to design spacecraft packing chest vibration measurement system. Using sufficient advantages of virtual instrument in vibration measurement，development cycle was reduced and testing cost was saved. Realized real-time data acquisition and storage for a long time，and displayed accelerated wave instant. Spectral analysis，key-points high-light display，extremum search，virtual value analysis and damping effect analysis of accelerated data were all based on basic theory of signal processing. At last， reviewed collection data，and generated report forms of extremum，virtual value， damping effect and printed them.

Key words: Vibration measurement；Acceleration sensor；Data acquisition；Virtual instrument；LabWindows/CVI
