| 摘 要： | 介绍了水下爆炸；中击波的概念特征和气泡脉动理论，根据此特征确定了水下冲击波超压测试系统的测试原理、采样参数等。系统将压力传感器、适配电路、A／D转换器、触发控制电路、通讯接口及电池紧凑封装在密闭、防水、坚固的钢壳内，构成一种可相对独立工作的便携式水下冲击波超压测试仪。该系统具有小体积、微功耗、采样频率高等特点，具有抗干扰性强和无需电缆引线的优点，特别适宜于大范围多测点的试验场合。 |
| 关 键 词： | 水下爆炸 冲击波 压力 测试方法 |

| Abstract: | The conception and characteristics of underwater blast shock wave and gas bubble pulsation theory are explained in this paper, based on which,the measuring principle and sampling parameters of the overpressure measuring system of underwater blast shock wave are figured out. The underwater blast pressure sensor,A/D converter, trigger control circuit, communication interface circuit , battery and other circuits are packaged in an airtight, water-proof and solid steel shell, which make up of a underwater blast shock wave measuring system working independently. This system has advantages of small size, low power consumption , high sampling frequency, anti-interference and no-need of cable, and is fit for large-scale multi-point measurement in underwater. |
| Keywords: | underwater explosions blast shock wave pressure measurement |
