在弹体高速侵彻硬目标过程中,弹载测试装置往往因承受高过载而工作失灵,为保证在高过载环境下测试装置的存活性,文中利用薄壁金属管结构对测试装置进行隔离保护,并进行了空气炮实验。以隔冲效率、体积比吸能、质量比吸能和载荷效率等4个指标来评判薄壁金属管的缓冲效能。结果表明,以锥角为15°的薄壁金属管结构具有最佳缓冲性能。

The missile-borne test device often fails to work in the process of high-speed penetration of projectile into hard target because of the high overload. In order to ensure the viability of the test device in the high overload environment, the test device is buffered and isolated by the thin-walled metal tube and air gun test was carried out in this paper. The buffering efficiency of thin-walled metal tube is judged by four indexes, such as the separation efficiency, the volume specific energy absorption, the mass ratio energy absorption, and the load efficiency. The results show that the thin-walled metal tube with cone angle of 15 degrees has the best buffering properties.
