The Experimental Research of the Multi-Layered Spaced Protective Structure with Stiffeners Penetrated by Projectile

摘要

The experimental study method of the multi-layered spaced protective structure with stiffeners,which is called structural target,is presented penetrated by projectiles in this paper.Many parameters of the terminal ballistics effects and damage model of structural target are obtained after the experiment in which experimental projectiles are used to penetrate the target with stiffeners and steel plate target vertically,offering the basic experimental phenomenon and data for the mechanism research of projectile penetrating structural target (protective structure with stiffeners).In the meantime,the effect of the stiffeners on the failure mode of the structural target and the effect of the thickness and stiffness of stiffeners in the structural target are analyzed preliminarily.This paper could be helpful in the design of the protecting structures.
