【摘要】 为客观、直观地评价战斗部的威力,提出了一种水泥板破碎距离评价法.在实验研究的基础上,根据结构动力学原理,对爆炸载荷作用下水泥板的结构动力响应问题进行了分析.给出了水泥板破碎距离的一般计算式以及冲量载荷、准静态载荷情况下的简化计算式,并与实验结果进行了比较.结果表明,计算值与试验结果基本一致,文中提出的计算方法正确且能够满足工程需要.更多还原

【Abstract】 A method for an objective evaluation the force of warheads upon the crushing distance of slabs of reinforced concrete is proposed.Dynamic responses of slabs under the explosion loading are analyzed in terms of the principle of structural dynamics after an experimental study.General formula and specific simplified formulas for calculating the crushing distance are derived.Comparison between calculation and experimental results show that the method proposed is correct and satisfies the engineering requirements.更多还原
