摘要:针对由多个爆炸螺栓组成的分离系统的分离故障定位问题，设计了一种基于激光反射的分离反馈装置，根据检测反射光强度判断各个爆炸螺栓是否分离。通过将反馈装置与爆炸螺栓上反射膜错位或重合，来模拟爆炸螺栓的分离或发生故障，并对反馈装置功能进行试验验证。结果表明：错位时反馈光强低于100nW，重合时反馈光强大于100nW，从而可对分离故障位置进行准确定位。
Abstract:Aiming at the separation fault location problem of the separation system composed of multiple explosive bolts, a separation feedback device based on laser reflection was designed, and each explosive bolt was separated or not can be judged by detecting the intensity of reflected light. The feedback device and the reflective film on the explosive bolt were staggered or overlapped, to simulate the separation or failure of the explosive bolt, and the function of the feedback device was tested and verified. The results show that when the two positions are staggered, the feedback light intensity is less than 100nW, when the two positions are overlapped, the feedback light is stronger than 100nW, so that the separation fault can be accurately located.
