排爆罐作为常用的公共安全防护装备,其结构的抗爆性能机动性等指标对安全保障起到决定性作用.目前国内常用排爆罐结构笨重,质量较大,抗爆性能较差.为研制一种新型便携式轻质高抗力排爆罐,制作泡沫铝夹心排爆罐模型,与国内既有排爆罐模型开展相同装药量条件下的抗爆性能对比试验.对结构中应力波的衰减特性进行了分析,探讨了影响排爆罐抗爆性能的核心因素.比较表明,泡沫铝夹心排爆罐抗爆性能远优于传统排爆罐.%An explosion-proof pot is a common protection equipment in poblic safety fields, its antidetonation property and mobility are critical for safety protection.At present, explosion-proof pots made in China are heavy and massive, their performance is worse.In order to make a portable pot with new style and higher antidetonation property, sandwich pot models with aluminium foam were manufactured, and tests were accomplished to verify their antidetonation property compared with domestic traditional explosion-proof pots.Fading characteristic of stress wave in the sandwich structures were analyzed.Key factors influencing the antidetonation ability of explosion-proof pots were discussed.Tests results indicated that antidetonation property of pots with new style is more excellent than that of traditional pots.
