| 摘 要： | 采用试验与数值模拟相结合的方法，对爆炸冲击波作用于防爆墙的载荷与冲击波绕过防爆墙的规律进行了研究. 采用压力传感器测压技术获得了防爆墙前后不同距离的压力曲线.数值模拟基于ALE方法与JWL状态方程，试验结果与数值模拟基本相符，给出了冲击波作用于防爆墙迎爆面上的载荷并研究了冲击波绕过防爆墙详细过程. 通过综合分析，得到了爆炸冲击波绕流的内在机理为防爆墙的设计与加固提供依据和参考.

| Abstract: | Experimental and numerical investigations were performedon explosive shock wave around the wall and explosive loads on theprotective wall. The transducer pressure measurement technology was adoptedto measure the pressure distribution around the protective wall. Pressurehistory on the forward and backside of the protective wall was gained, Basedon ALE algorithm and JWL state equation, a numerical simulation was carriedout to simulate the above complex phenomenon of mechanics of explosion. Bothexperimental and numerical results are in good agreement, which show theinherent mechanism of blast wave around the wall and provide a reference forreinforcement mechanism study of the protective wall. |
