摘 要:本文介绍了一款防地雷反伏击车车底防护结构的设计方法,并通过计算、仿真和试验验证的手段,模拟了爆炸冲击载荷作用的过程,分析了防护结构对爆炸冲击波的影响和对人员的保护作用。最后,在国内某权威试验场,我们根据STANAG 4569相关标准和要求,进行了全尺寸爆炸冲击试验,试验中对乘员在发生车体下爆炸事件时的被动安全水平进行了测试。在受到8kgTNT当量的爆轰型地雷替代装药爆炸后,车辆主体结构完整,舱体内部底板和车体顶部基本平整,未出现贯穿性裂纹,充分验证了该结构的防护性。

Abstract: This paper introduces the design method of the protective structure of the vehicle bottom of a mine resistant ambush protected vehicle. By means of calculation, simulation and experimental verification, the process of the explosion shock load is simulated, and the influence of the protective structure on the explosion shock wave and the protection effect on personnel are analyzed. Finally, according to the STANAG 4569 standard and requirements, a full-scale explosion impact test was carried out in a domestic authoritative test site. In the test, the passive safety level of passengers in the case of explosion under the car body was tested. After being blasted by 8 kg TNT equivalent explosive charge, the main structure of the vehicle is complete, the interior bottom plate and the top of the vehicle body are basically flat, and there is no penetrating crack, which fully verifies the protection of the structure.

1 前言
在当前国际以和平和发展为主题的大局势下,局部冲突、小规模战争仍时常发生,军用地面车辆面临的威胁仍然存在,甚至情况愈演愈烈,最为常见的有简易爆炸装置(1ED)和地雷等。二十一世纪以来,国际局势的变化使得世界各国军队基本职责已经由大规模军事行动转变为反恐、防暴、维和、救灾等小规模行动为主,各国陆军部队面临大量反恐、防暴作战任务的考验,如:阿富汗和伊拉克的治安战,阿拉伯国家的内乱等新的军事行动。西方国家的军事系统已察觉到仅仅采用附加装甲的防雷车辆方案已无法应对现代战场的需要,因此迫切需求研发出一种防护性、机动性都较高的军用防雷车辆,由此诞生了防地雷反伏击车(MRAP)。……
