| 摘 要： | 风帽材料是影响PTFE/Al含能枪弹侵彻土壤深度的一个重要因素，为了研究风帽材料对PTFE/Al含能枪弹侵彻土壤深度的影响，采用弹道枪垂直侵彻土壤的试验方法，设计了单一变量对比试验，在相同枪弹外形、初速及土壤组分情况下，对比分析尼龙、铝合金、钢、PEFE/Al四种风帽材料的PTFE/Al含能枪弹侵彻单位距离所需的能量，获得最大空腔位置与侵彻深度的关系.试验结果表明，延迟PTFE/Al含能材料激发时间有利提高PTFE/Al枪弹侵彻土壤的深度，采用铝合金风帽材料的PTFE/Al枪弹侵彻单位距离土壤所需能量最小.

| Abstract: | The material properties of bullet head have an important influence on PTFE/Al bullets penetrating into soil. To investigate the relationship between bullet head material and penetration depth, bullet heads made of nylon, aluminum, 45#steel and PTFE/Al were shot by ballistic gun and penetrated vertically into soil. By contrastively analyzing the penetration energy per unit distance, the mathematical relation between the location of the biggest cavity and penetration depth was obtained. The result shows that aluminum bullet head need minimum energy, and delay PTFE/Al active time will enhance penetrating depth. |

| Keywords: | PTFE/AL reactive material bullets soil penetrate depth |
