In the armor protection materials research and manufacturing process, the need for the design of the armor protective material impact test, so as to detect the product"s protective performance. The existing methods of armored protective material can only be qualitative analysis, can not be quantitative analysis. Aiming at the problem that the traditional impact detection system is complicated, the data processing is cumbersome and the cost is high, an impact detection system based on LabVIEW is designed. The system realizes real-time data acquisition, real-time display, automatic storage, playback and completely records the impact of the impact of the size of the impact and its changes in the process. The system is stable, high precision, low cost, to meet the requirements of modern testing.
