Abstract

Abstract: Because of the space experiments of various countries, there are so many small pieces of debris in space, leading to the accident of spacecraft. Through AUTODYN software numerical analysis and SPH method, a numerical simulation study was carried out on the failure mode of the cylinder projectile impacting the double-layer ceramic target plate of aluminum alloy and boride base superhigh temperature composite ceramic at ultra high speed. The variation of perforation radius of the projectile against double target plate was obtained. The paper concludes that, in the failure mode of different mass projectiles striking double target plate, the total perforation radius of the second layer boride base superhigh temperature composite ceramic target increases first, then decreases and finally explodes.
