助推钻地弹侵彻混凝土的工程分析和计算

ENGINEERING ANALYSIS AND CALCULATION ON CONCRETE PENETRATION BY EARTH PENETRATING WEAPON WITH ROLL BOOSTER EFFECT

钻地弹在现代战争中的大量运用已对坚固地下目标的生存性构成严重威胁 ,助推技术是提高钻地弹动能和侵彻能力的关键技术 .以土盘浮动锁应变模型为基础 ,在侵彻计算中考虑了助推因素对钻地侵彻能力的影响 ,发展了一种分析助推钻地弹侵彻问题新的工程近似方法 .通过侵彻混凝土靶的算例 ,来比较和验证助推对侵彻过程的影响 。

Extensive application of earth penetrating weapon (EPW) in modern war has been severely threatening the viability of strong underground targets, and the roll booster technology is a critical method to improve kinetic energy and penetration ability of EPW. On the basis of soil disc and floating lock strain model, and engineering analysis on penetration problem with roll booster effect is developed. Several numerical examples about penetration into concrete targets are presented and the results are used to verify and reveal the effect of the rocket, also the effectiveness and feasibility of the method are explained.
