地形环境对冲击波传播规律影响研究综述

Summary of researches on the influence of terrain environment on the law of shock wave propagation

爆炸场周围地形环境不同会直接导致冲击波压力传播规律发生变化,明确不同地形环境对爆炸冲击波传播规律的影响作用对准确评估冲击波毁伤威力及指导实战过程中弹药的选用具有非常重要意义。综述了爆炸冲击波在巷道、隧道、密闭空间、舱室、坑道及壕沟内的实测及有限元数值仿真分析冲击波压力传播规律,指出了目前常见的几种地形环境对冲击波传播规律影响研究中存在的不足,提出了后续研究中应该着重分析的问题,并指出后续研究所需解决的关键技术。

Different terrain environments around the blast site will directly lead to changes in the propagation law of shock wave pressure.It is of great significance to clarify the influence of different terrain environments on the propagation law of blast shock waves to accurately assess the damage power of shock waves and guide the selection of ammunition in actual combat.Paper summarizes the actual measurement and finite element numerical simulation analysis of shock wave pressure propagation law in tunnels,tunnels,confined spaces,cabins,tunnels and trenches.Points out the terrain environment effect on shock wave propagation law of the defects in the research,put forward the follow-up study should focus on the analysis of the problems,and points out that to solve the key technology of subsequent research institute.
