摘要
为研究微起爆序列中结构间隙对传爆性能的影响,基于有限元分析方法,建立了微起爆序列仿真模型,并运用JWL和Lee-Tarver方程进行计算,得到了起爆二级药柱的3种尺寸微药柱的临界间隙值。将仿真结果进行试验验证,结果表明仿真结果能够准确地反映实际情况。
In order to study the effect of structure clearance on detonation capability of micro explosive train, the twodimensional simulation model of micro explosive train is built using the finite element analysis method, and the calculation was carried out using the JWL and Lee-Tarver equation. The critical clearance value for first grain with three diameters were obtained.Then, the simulation result is tested and verified, which shows that the simulation can accurately reflect the actual situation.
