3D打印成形弹体侵彻钢板的实验研究

Experimental Study on Penetration of 3D Printing Shaped Projectile into Steel Plate

采用金属3D打印技术,设计了一种头部风帽与壳体复合的弹体结构,对传统机械加工和3D打印成形两种方法制造的弹体进行了高速侵彻钢板的实验研究。结果表明,相比较传统机械加工技术,3D打印技术制造的壳体也能保障侵彻弹体顺利贯穿多层钢板,且保持弹体结构和功能正常,该技术可为实际工程中侵彻壳体的大批量、短周期试制提供快捷、扎实条件保障。

Based on the development of metal 3D printing technology,a shell structure composed of hood and shell was designed,and the high-speed penetration of steel plate by projectile made by traditional machining and 3D printing was studied.The results show that,compared with the traditional machining technology,the shell made by 3D printing technology can also ensure the penetration of the projectile through the multi-layer steel plate smoothly,and keep the structure and function of the projectile normal.This technology can provide fast and solid conditions for the large-scale and short period trial production of the penetration shell in practical engineering.
