Numerical and Experimental Investigation on Penetration Effects of Semi-Armor-Piercing Warhead;

Based on the research experience of semi-armor-piercing warhead,integrated design method for SAPW was studied by advanced engineering design method and computer technique.

The head thickness design of the semi-armor piercing warhead is calculated and analyzed applying the Dimen- sional-Analysis and Similitude-Law as well by the experiment data gained in the cylinder bumping experiment,the rela- tionship curve between the length of the distorted part and its velocity is gained that can be as one of bases while desig- ning the semi-armor piercing warhead.

According to the structure of aircraft carrier and existing anti-ship missile warhead,the structural target with ribbings and experimental half-penetrating warhead were designed with geometer similar principle.

It has known well armour-piercing damage by armour-piercing warhead,yet it has discussing kinetic energy damage to hit.

Researched armour-piercing warhead penetration process with the way of numerical simulation based on LS-DYNA, it was a program that analyse dynamics.

Precision shaped charge warhead technology is a major way to improve the penetration power and stability, which consists of following key techniques: powerful explosive, precise charge, precise liner and precise assembly.
