为研究杆条破片对薄靶板的切割毁伤特性,对杆条切割毁伤特性的影响因素进行了分析,建立了高速杆条对薄靶板切口长度的投影计算模型,模拟了典型入射条件下杆条对薄靶板的切割毁伤。分析指出杆条对薄靶板的切割毁伤特性除了受杆条和靶板的自身因素影响外,还受到杆条着靶速度、攻角、入射角及面角等入射条件的影响。当攻角大于15°时,投影计算结果与模拟计算结果差值在10%以内,投影计算模型可用于目标易损性分析。

To study the incision characteristic of rods on thin target, the pertinent parameters were analyzed, a projection method about rods' incision length on thin target was constituted, and the penetration process of rods on plane target was simulated. It indicates that the incision characteristic of rods on thin target is influenced by rods' velocity, attack angle, incident, angle and surface angle. When the attack angle is more than 15°, the difference between rods' incision length got by projection method and. by simulation is less than 10%.
