摘要
本文研究实弹射击防弹头盔的打击力计算，描述防弹头盔的测试装置。将该装置分成两个系统：导弹和钢盔及头模为一系统，应用动量定理计算其打击力；头模和测力传感器连同支承杆为一系统。利用文献［１］对防弹衣模拟靶（木模）的动态应变和位移的测定，计算弹击时头模的变形能和动能；同时计算弹击时测力传感器所作的功和支承杆消耗的能量；根据能量守恒原理计算防弹头盔的打击力。计算结果与实测值基本一致。文中所得的结果已应用在ＧＧＫ９３Ｔ型防弹头盔等系列产品的设计中。
In this paper the hit force on bulletproof helmets has been computed and the test device has been described. The device is divided into two parts: (1) The bullet helmet and mould are in one system, using moment theorem to calculate the hit force; (2) The mould sensor and support pole are in one system, using the method in reference 1 that measures the dynamic strain and displacement of simulate target of bulletproof clothes. We compute the transfigure energy and momentum energy while hitting the mould, the work done by sensor and the expend energy of support pole. We get the hit force of helmet using energy balance principle. The resolute is according with the test. The resolute has been used in designing the GGK93 bulletproof helmet and other serial products.
