摘要

本研究係以仿生魚鱗結構的排列方式，提出防護裝甲設計。實驗部分利用0.30＂穿甲彈實施彈道測試，透過量測穿靶前後速度計算厚度與組合對靶板能量吸收之影響，實驗結果顯示，在圓形裝甲片同為9 mm厚度下，由8 mm厚陶瓷片搭配1 mm厚圓形鋁板之組合抗彈能力優於其他組合之靶板。模擬部分使用LS-DYNA軟體模擬鱗甲構型靶板受彈頭穿靶時之能量吸收、陶瓷破壞情形、應力傳遞方式、彈頭餘速等，顯示數值模擬結果的合理性。

In this research, we proposed the armor design based on the arrangement of bionic scale structures. The ballistic test was under a 0.30＂ armor-piercing bullet impact. The energy absorption was calculated by measuring the velocity before and after the impact. The experimental results showed that the 8 mm alumina with 1 mm aluminum disk combination had the best impact resistant performance among all the specimens when circular armor disks was fixed at 9 mm thickness. The energy absorption, damage state, stress transmission mode, and bullet residual velocity of the armor penetrated by projectile were investigated by a finite element model using LS-DYNA, showing the rationality of the numerical simulation results.
