摘　　要：应对高速侵彻高冲击的主要措施之一是加垫片,而已有垫片材料并不理想。为此,提出以新型材料泡沫铝制造高超音速侵彻引信垫片,泡沫铝自身内部多孔结构有利于抗高过载冲击。ANSYS/LS-DYNA有限元仿真表明,6 mm泡沫铝垫片能起到较好的抗高过载冲击作用,但计算得出的垫片厚度仍不理想,可能需要从衰减应力波角度进一步研究。Usual treatment of dealing against the fierce shock while high speed penetration is to add gasket,but the effect of common material is not ideal.Few research has been done on anti-shock of foamed aluminium in hypersonic penetrating fuze so far.The spongy structure of foamed aluminium is beneficial to mechanical filtering.In this paper,foamed aluminium was used to make the gasket for hypersonic penetrating fuze.The simulation result indicated that 6 mm gasket could effectively attenuate the over pressure of shock wave,but the thickness was not suitable.The further reseach is to be done on attenuating stress wave.
