The Process Performance Of A Man-heat Shaped Charge Liner

On the basis of theory analysis of influence of liner performance on HEAA shell penetrability, the article has discussed fully the technological property of HEAA shell liner through the method of experiment research combining with theory analysis. The study results have shown the influence of the grain size, coaxiality and wall thickness tolerance of liner on armor-piercing power of HEAA shell. The more fine grain size becomes, the more long the effective continuous jet length would become so that break-up time of jet would delay and power of static armor-piercing power would increase. The more small the coaxiality and wall thickness tolerance become, the more beneficial the effective continuous metal jet would form and the more beneficial the armor-piercing ability would increase. The article has studied the factors which influence liner property through the method orthogonal test finally. It has shown that wall thickness tolerance is the most primary factor affecting liner property, playing a decisive role in the armor-piercing penetration power.
