为研究聚氨酯泡沫和液体结构的抗爆特性,设计了填充聚氨酯泡沫球、环形聚氨酯泡沫、环形聚氨酯泡沫-液体顶盖和填充式聚氨酯泡沫球-液体四种典型防护结构,开展试验和数值仿真研究,分析不同结构在冲击波压力峰值和火焰防护方面的特性,研究结果表明,采用填充式的聚氨酯泡沫球-液体结构,单位体积和单位质量的防护效率均较优,冲击波压力峰值较空爆下降77.7%,火焰在0.6ms时刻全部熄灭,相关防护结构有较好的应用前景。
This study investigates the blast resistance characteristics of polyurethane foam and liquid structures. Four typical protective configurations were designed: filled polyurethane foamball
annular polyurethane foam
annular polyurethane foam-liquid cover
and filled polyurethane foam ball-liquid. Experimentsand numerical simulations were conducted to analyze the performance of these structures in terms of shock wave peakpressure and flame protection. The results indicate that the filled polyurethane foamball-liquidprotectiveconfiguration exhibits superior protective efficiency per unit volume and mass
with a 77.7% reduction in shock wavepeakpressure compared to air blast. Flames were completely extinguishedat0.6 ms
demonstrating promising application prospects for these protective structures.
