Description

一种平板对开式单机掩蔽库防护门
技术领域
本发明属于掩蔽库防护技术领域，具体涉及一种平板对开式单机掩蔽库防护门。
背景技术
北约国家空军基地主要采取分散建设单机掩蔽库以保护飞机，从上世纪60年代开始修建单机掩蔽库至今，单机掩蔽库的防护门经过了不断改进和升级：防护门的设置由内置式发展成外贴式；启闭方式由立转式到推拉式。在防护抗力方面，第一、二代防护门整体抗冲击波超压能力在0.1MPa以内，基本没有承受炸弹破片直接打击能力。经过不断改进和加强防护门研制，实现第三代单机掩蔽库防护门整体抗冲击波超压能力在0.3MPa以上，具有抗炸弹近距离***破片的直接打击能力。
与西方军事强国相比，我国防护工程研究起步较晚，但发展较为迅速。早期，我国单机掩蔽库防护门，采用钢桁架—CF80钢纤维钢筋混凝土平板组合式推拉门设计，整个门体宽度达4.5米，总重130吨，只能设置在飞机掩蔽库顶端，不能内置。第三代单机掩蔽库防护门采用外置式推拉防护门，外置钢桁架、门板采用CF80钢纤维钢筋混凝土与钢板复合结构，设置于机库顶端，目标暴露，易遭武器直接命中打击。***单机掩蔽库防护门采用“内缩式外倾翻转”结构，面板为40mm F20钢+抗爆混凝土+背撑板，结构重量大，启闭时间长。
传统防护门多采取钢筋混凝土与钢板复合结构，面密度高达500kg/㎡，较大质量增加了防护门的启闭机构与连接位置压力，连接结构与启闭机构抗冲击载荷压力增大，启闭时间长。
传统防护门的技术缺点：1)使用钢筋混凝土材料制作防护门重量大；2)防护门启闭时间长。
发明内容
本发明提供一种平板对开式单机掩蔽库防护门，要解决的技术问题是：在保证防护的前提下，解决防护门重量大和抗力低的问题。
为了解决以上技术问题，本发明提供了一种平板对开式单机掩蔽库防护门，其特征在于：采用装甲钢与复合材料层间组合，防护门从迎爆面至洞库内结构依次为：防护门面板1、PE吸能层3、吸能缓冲层4和装甲钢背板5；防护门面板1与PE吸能层3之间设有间隙。
有益效果：本发明通过采用层间材料机构间隙效应，设计一款轻质、高抗力平板对开式复合防护门，门板面密度不大于350kg/㎡(含连接件)，按照冲击波根据***相似率准则，按10kgTNT距离防护门1.4m地面***模拟1000磅MK83***冲击波超压，***后，门体不贯穿，能够正常启闭。极大的减轻了防护门门板的重量，缩短了防护门的开启时间。对传统钢结构防护门进行轻量化设计和提升复合材料防护门的抗爆性能。门板采用装甲钢与非金属复合材料制作而成，设计门板各层材料间隙组合，利用结构间隙效应，剂保证了防护门整体的抗冲击超压能力，有减轻了防护门的整体质量，开启方式采用外置推拉式，加速启闭时间。
附图说明

图2防护门结构示意图。
具体实施方式
为使本发明的目的、内容和优点更加清楚，下面对本发明的具体实施方式作进一步详细描述。
本发明提出的一种平板对开式单机掩蔽库防护门6，采用装甲钢与复合材料层间组合，防护门由迎爆面至洞库内结构依次为：防护门面板1、间隙支撑框架2、PE吸能层3、吸能缓冲层4和装甲钢背板5；防护门6通过门框7设置在洞库8外。
防护门面板1采用10-20mm6211装甲钢，防护门面板1与PE吸能层3之间设有15-25mm间隙，该间隙通过间隙支撑框架2支撑实现，PE吸能层15-25mm UHMWPE膜复合板，吸能缓冲层采用20-30mm蜂窝铝结构，装甲钢背板采用5-15mm616mm装甲钢，如图1所示。可以有效抗1000磅MK83距离门5m***的破片与冲击波杀伤，保护洞库内飞机、设备与人员的安全。
设计第一层迎爆面与复合材料层之间存在20mm间隙，利用间隙效应达到防护目的。第一：阻隔应力波，在第一层装甲钢受到高速撞击并在其内部产生应力波时，该应力波向背面传播。在装甲钢的背面与空气的界面上产生全反射。这样就减少应力波传递到第二层复合材料层上，使其不受应力波的作用。第二:隔力，在间隙结构中，当装甲钢受到外部机械力作用时，在内部产生力的传递，但在装甲钢背面时，由于空气的阻隔，这种机械力不能传递到第二层复合板，使其不受外力作用。第三：泄压，当受到冲击时，装甲内部受到巨大的压力，由于空气的极大的可压缩性使间隙成为良好的缓冲层和泄压空间。第四：打击物***空间，在大间隙结构中，当间隙的水平间距大于固体打击物长度时，该打击物可以在间隙内***，有可能使其飞行姿态失稳降低打击物穿透能力。第五：阻止裂纹的扩展，在间隙结构中，当第一层装甲钢产生裂纹时，由于界面的存在，裂纹不可能传递到第二块装甲板上，其扩展受到截止。
设计第二层20mm PE复合板+24mm吸能缓冲层(蜂窝铝)，主要负责吸收剩余冲击波与高速破片拦截，利用其快速对***冲击波进行衰减与轻质、吸能效能高、应变波传输速度高的特性。
设计第三层10mm616mm装甲钢，负责第二层缓冲吸能层的高强支撑，以及高速破片的拦截。
本发明采用装甲钢与复合材料层间组合，防护门门板由迎爆面至洞库内结构为：15mm6211装甲钢+200mm间隙+20mm UHMWPE膜复合板+24mm吸能缓冲层+10mm616mm装甲钢，间隙支撑框架采用200mm矩形钢框架。
本发明轻质高抗力复合材料防护门采用层间材料机构间隙效应，在保证防护的前提下，极大的减轻了防护门门板的重量，缩短了防护门的开启时间。
本发明洞库防护门作为洞库防护的第一道屏障，是敌重点打击且极易造成破坏的部位，其功能发挥的程度直接影响洞库的整体防护效能。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变形，这些改进和变形也应视为本发明的保护范围。
