舰艇舱室内爆炸超压检测系统设计及其动态验证

为了在有限的舰艇舱室空间内实现对爆炸冲击波超压的有效检测，设计了一种体积小、功耗低、响应快的集成模块化自适应存储式舰艇舱室内爆炸超压检测系统。概述了系统的基本组成，给出了超压检测系统的硬件组成，主要包含了电源硬件模块、信号调理模块、存储模块以及触发模块等部分。设计了一个内径为0.8 m，长0.8 m，壁厚12 mm的舰艇舱室模拟装置，并在5 g及6.8 gTNT柱形装药下进行了内爆炸动态验证试验，分别测得4个不同位置处的超压数据信号，基于内爆炸分析理论，证实了超压数据的合理性，同时也验证了本文设计的超压检测系统的有效性。该系统为深入研究舰艇舱室内爆炸冲击波流场的变化、荷载分布及舰艇机电设备的防护提供了技术支撑。

System design and dynamic authentication for inner explosion over pressure detection at warship cabin

In order to achieve effective detection of over pressure explosion in the limited warship cabin, the adaptive storage over pressure detection system with small size, low power consumption and fast response type of integrated modular is presented in this paper. The basic components are summarized,and the hardware components of over pressure detection system are also given, which main include the power hardware module, signal conditioning modules, memory modules, and the trigger module. The simulator of warship cabin is designed with inner diameter of 0.8 m, length 0.8 m and wall thickness 12 mm, the dynamic verification tests are promoted in 5 g and 6.8 g TNT, the over pressure measured data signals at four different positions are obtained. Based on inner explosion theory, Based on internal explosion theory, it confirmed the validity of over pressure data signal, and also to verify the effectiveness of over pressure detection system. This system provide a technical support for study the changes in warship cabins blast flow field, load distribution and electromechanical equipment.
