【摘要】：针对脉冲信号电探针在微喷射物质作用下出现的"非正常"放电现象,提出了微喷射物质K+Rx等效电路模型,用以解释微喷射物质导通电探针放电机理。开展爆轰实验,联合X射线测试技术,确定了电探针放电区域处于微喷射区与微层裂区的过渡地带,并发现电探针的3类"非正常"放电现象。建立电路仿真模型,将微喷射物质等效成K+Rx电路,调节K+Rx等效电路模型参数,模拟电探针的3类"非正常"放电现象。仿真结果表明,K+Rx等效电路模型很好地解释了微喷射物质作用下脉冲信号电探针的放电机理。
[Abstract]:In view of the "abnormal" discharge phenomenon of the pulse signal electric probe under the action of micro-ejector, a K Rx equivalent circuit model is proposed to explain the discharge mechanism of the micro-jet material conduction probe. The detonation experiment is carried out. Combined with X-ray measurement technique, the transition zone between the micro-jet region and the micro-spallation region is determined, and three kinds of "abnormal" discharge phenomena of the electric probe are found. The circuit simulation model is established. The micro-injection material is equivalent to K Rx circuit, and the model parameters of K Rx equivalent circuit are adjusted. The simulation results show that the K Rx equivalent circuit model can well explain the discharge mechanism of the pulse signal electric probe under the action of micro-ejector.
