摘要:
为研究微传爆序列结构中隔板对其传爆性能影响,采用有限元分析方法，模拟了微小直径药柱(以CL-20和JO-9C作为一级、二级装药，直径分别为2 mm和4 mm，径高比为1)在镍和不锈钢材料下，不同隔板厚度对微序列起爆传爆能力的影响。得到了CL-20起爆JO-9C装药时这两种材料隔板的临界起爆厚度，分别为1.6 mm(不锈钢)、1.4 mm(镍)，材料镍的隔爆能力优于不锈钢。对仿真结果进行了试验验证，结果表明，该仿真能够较准确地反映实际情况。
Abstract:
In order to clarify the detonation property change of micro sequence brought in by the gap materials, the finite element analysis method was used to simulate the initiation and detonation capability of the micro sequence for small diameter sample shielded by nickel or stainless steel gaps at various thickness. CL-20 and JO-9C were respectively used as primary column and secondary column.Their diameters were 2 mm and 4 mm, and the ratio of diameter to height was 1. The critical thickness at which these two materials will ignite were obtained as 1.4 mm for nickel and 1.6 mm for stainless steel. Nickel has a better antiblast capability in comparison to stainless steel. Simulation results were verified by corresponding experimental measurement, indicating the high accuracy of this simulating method to reflect the actual conditions.
