摘要

摘要: 扩爆装药结构对爆轰波传播、飞片驱动过程以及对主炸药引爆性能有直接的影响。为分析装药结构对飞片威力参数的影响，针对装药直径、飞片厚度、飞片拱起高度等主要结构参数，利用正交实验原理设计了数值实验方案，并采用动力学有限差分程序建立了相应的数值模拟模型。通过对数值实验结果的对比和统计分析，获得了影响飞片速度、动量、比动能等引爆炸药威力指标的主要装药结构参数及其影响规律。其结果可为相关扩爆装药设计提供理论依据。

Abstract: The booster charge structure has direct effects on the detonation wave propagation, the driven flyers and the shock initiation performance. To analyze the influence of the booster charge structure on the performance parameters of the flyer power, a numerical simulation scheme was designed based on the orthogonal test principle in view of the 3 structural parameters, including the flyer thickness, the charge diameter and the flyer height. The AUTODYN3D finite difference program was used to establish the corresponding numerical model, and the main charge structure parameters influencing the flyer velocity, momentum and kinetic energy indexes were obtained through statistical analysis of the simulation results. The analyses and results provide a theoretical basis for the design of similar booster charges.
