基于数值模拟的双层防爆墙抗爆效果研究

Research on the Anti-Explosion Effect of Double-Layer Explosion-Proof Wall Based on Numerical Simulation

使用LS DYNA软件对拟设计的双层防爆墙的抗爆性能进行数值模拟,分析1800kg的TNT在单层防爆墙以及双层防爆墙下的超压分布情况,评价单层、双层防爆墙的抗爆性能,随后对40kg当量的TNT在第一层防爆墙后爆炸的情况进行模拟,分析第二层防爆墙的消波性能,从而得出双层防爆墙的设计可用性。

Uses LS DYNA software to simulate the explosion resistance of the double-deck explosion-proof wall to be designed,analyzes the overpressure distribution of 1800kg TNT under the single-deck explosion-proof wall and double-deck explosion-proof wall,evaluates the explosion resistance of single-deck and double-deck explosion-proof wall,models the explosion situation of 40kg equivalent TNT behind the first-deck explosion-proof wall.Analyzes the wave attenuation performance of the second layer explosion-proof wall,and obtains the design availability of the double layer explosion-proof wall.
