The amount of road vibration PSD data through actual measurement is large and complex due to route diversity. It is difficult to apply in practical engineering. A road spectrum management system was developed using Visual Basic 6.0 as interface language and SQL Server 2000 as backstage database to make full use of the actual measurement data in packaging test. The software achieves all of the steps of test spectrum of actual environment spectral data to the laboratory process. It also sets up different database according to data processing steps respectively. The database can satisfy the requirement of data expansion and updating in future.
