聚奥-9C装药的传爆管殉爆
Sympathetic detonation of booster pipe with JO-9C charge
摘要
Abstract
In the present study we carried out sympathetic detonation experiments,using RDX-8701 as donor and booster pipe and using JI-9C charge as acceptor explosive,to study the response of the fuse explosion device under shock wave.By observing the remainder of the JI-9C explosive,the deformation of the witness and the steel shell,and judging the explosive reaction state,we analyzed the histories in the sympathetic detonation reaction of the acceptor,and established the calculation model of the sympathetic detonation using AUTODYN.The calculated results of the model included the effects of the shock waves produced by the donor that acted on the booster pipe.Based on the fluidsolid coupling method,we also obtained the critical and safety distance of the sympathetic detonation through numerical simulation by adjusting experimental distance.The results show that the detonation wave propagated down firstly along the slope direction of the booster charge,thereby leading to the detonation of the booster charge,and then detonated the detonator explosive.According to the numerical simulation results,the critical and the safety distances of the sympathetic detonation were 5.7 mm and 8.8 mm respectively.关键词
