摘要(Abstract):

为得到冲击波反射超压峰值沿刚性墙体高度分布的规律,利用AUTODYN软件建立数值计算模型并进行求解,并与美军常规武器防护设计手册(TM5-855-1)计算结果进行对比分析。通过拟合得到了刚性地面上不同比例距离处冲击波超压峰值沿刚性墙体高度分布的计算公式,可为防爆墙及结构抗爆设计提供参考。
In order to obtain the distribution of peak reflection shock wave overpressure along rigid wall,the finite element models were set up.The problems were solved by using AUTODYN software and analyzed by comparing with the calculation results of TM5-855-1.The prediction formula was conducted to calculate the distribution of peak reflection shock wave overpressure along rigid wall at different scaled distance.The prediction formula could provide a reference in design for explosion-proof walls and structural anti-blast.
