The test data's efficient management and reusing is a challenge for automotive NVH research.Based on analyzing the characteristic of automotive NVH test data and requirements of test data management,a set of structurization method for test data of commercial testing system and handwork test,and also solutions for unified definition of unit,data visualization and test object dynamic expansibility are presented.By means of those key techniques,a practical automotive NVH test data management system has developed. The two years' running of the system in NVH department and test department of a automotive engineering institute shows that the system can support the research of NVH and has better data accuracy and work efficiency. Those techniques are also adapt to build other noise and vibration test data managment or other automotive test data managment.
