Abstract: In order to solve the problems of low efficiency, heavy workload, error-prone data operation and inconsistent operation in various workshops by manual statistical analysis of track quality testing data, this paper designed and developed a track quality testing data analysis system based on Visual Basic(VB). On the basis of standardizing the idea, method, process and format of data analysis, the system implemented the functions of on-board bad alarm, automatic statistical analysis of on-board shaking instrument daily report, automatic generation of track control weak sections, workshop operation quality evaluation and so on, which reduced the workload, saved the analysis time, and improved the analysis quality and efficiency. The test proves that the analysis results of the system can guide production and improve the quality of equipment
