摘要
为了解决常规武器以任一攻角打击任一防护级别工程口部时毁伤工程量计算问题,考虑常规武器的侵彻与爆炸局部破坏效应,综合应用结构贯穿工程量、回填土(含遮弹层)坍塌工程量和结构震塌面积,确定掘开式工程口部毁伤工程量分析方法,编写Matlab通用计算程序。研究发现,同一武器造成的最大毁伤工程量,并不随命中速度的增长而增大,而是存在最不利打击情况。口部以侧墙贯穿破坏为主、顶板贯穿破坏为辅。设置遮弹层具有重要的工程防护作用,随着遮弹层抗侵彻能力不断增强,最大毁伤工程量呈下降趋势。爆心位置及装药量对毁伤工程量亦有影响。
To study the penetration and explosion gineering entrance damage quantity was obtained local damage effects,the analytical method of the civil en- by considering the structure perforation damage quantity, backfilled soil （including the shelter plate） landslide quantity and the structure spalling area synthetically. The universal computing code of the damage quantity was programmed by the Matlab language and the problem of calculating the damage quantity when any conventional weapon attacks certain protective grade engineering by any strike angle was solved. With the help of the computing code,it is found that the maxi- mum damage engineering quantity caused by a certain conventional weapon doesnlt increase with the im- pact velocity enhancing but exists a worst impact condition. The entrance damage caused in the form of sidewall perforation is the majority and the roof perforation damage is the minority. Shelter plate can exert important protective effect and the maximum damage engineering quantity decreases with the shelter plate anti-penetration ability enhancing. The damage quantity can also be influenced by the position of the explo- sion core and explosion mass.
