容器内爆炸多传感器测试系统的原理设计与应用

The Principle Design and Application of Multi-Sensors Testing System for Explosion in Container

为对炸药爆炸进行测量和监控,出于安全以及测试方便考虑,试验需要在爆炸容器中进行。由于测试任务的需要,试验中使用的传感器的类型及数量较多,包括各种压力传感器、应变传感器以及爆速传感器等,因此构建一个多传感器的测量系统就显得十分重要。文章给出了试验容器的基本结构,介绍了钢筒内化爆试验爆炸冲击波压力测试系统的原理设计与应用,构建了传感器、起爆和同步触发、爆速监测以及数据采集存储几个主要部分组成的测试系统,并对系统几个主要组成部分进行了详细的阐述。压杆测压解决了高压测量中的测量困难以及传感器使用效率低的问题,取得了良好的实际应用效果。

In order to measure the explosion impulsion of detonator, the experiment must be performed in the detonate container by taking safety and convenience of the detonate testing into account. Due to the task of testing, there are many types of sensors, concluding kinds of pressure transducers, stain transducers and detonation velocity sensors etc, so the construction of multl-sensors testing system is very important. The basic structure of the experimentation container is presented in this paper. The principle design and application of explosion shock wave testing system with a container is introduced. A testing system containing sensors, explosion and synchronization trigger equipments, data acquiring and saving agent is constructed. The constitution of the testing system is expatiated in detail. The using of stress bar in testing pressure solves the problem that it is difficult in testing high pressure and low efficiency in the using of pressure transducer. Favorable results are obtained in practice.
