小尺寸破片对单兵防护装备的侵彻研究

为了探究了小尺寸破片是否能有效穿透普通单兵防弹衣与防弹头盔,以球型破片为对象,利用试验得出了0.2g钨合金球型破片侵彻Ⅲ级防弹衣与Ⅳ级防弹头盔的极限穿透速度;通过数值模拟的方法得出了防弹衣与防弹头盔的等效Q235靶板厚度,并探究了质量变化对破片极限穿透速度的影响规律。上述研究结论对新型高效反步兵武器与单兵基本防护装备的研制与开发都有重要的参考价值。

Research on penetration of small size fragment to single soldier protection equipment

In order to find out whether the small size fragment can penetrate the ordinary single-soldier bulletproof clothes and bulletproof helmets effectively, the spherical fragment has been selected as the object, obtained the limit velocities of the 0.2 g spherical tungsten alloy fragment penetrating the level Ⅲ body armor and level Ⅳ bulletproof helmet. The thickness of Q235 equivalent targets of body armor and bulletproof helmet is obtained by the means of numerical simulation, and the influence rule of the fragment's mass on the limit velocity is investigated.The conclusions is important to the development of new anti-infantry weapons and soldier's basic protective equipments.
