摘　　要：PVDF(聚偏氟乙烯)及其共聚物压电计具有响应快、灵敏度高、测压范围宽等特点,是一种理想的冲击压力传感器。该文利用PVDF压电薄膜自制薄膜传感器,并进行落锤动态标定实验,实验结果表明,该薄膜传感器具有相当高的线性拟合度和较好的重复性,可以用于低压段冲击波压力测量。The polyvinylidene fluoride （referred to as PVDF） piezoelectric thin film is a new type of polymer piezoelectric materials. Because of its light weight, thin thickness, high sensitivity, high mechanical strength, wide frequency response range and other advantages,it has the application prospect in the explosion field. The film sensors are made based on the PVDF piezoelectric film as the sensitive element, and the low dynamic pressure calibration tests are conducted. The result shows that it has a very high linear degree and good reproducibility, and can be used for the shock wave pressure measurement in the low pressure section.
