摘　　要：屏蔽运输容器能够保证放射性废物运输的安全。在我国,高密度聚乙烯高完整容器(HDPE-HIC)作为一种新型货包,暂无专用的屏蔽运输容器,开发一套用于HDPE-HIC的屏蔽运输容器,可防止放射性废物转运、运输过程中对外界产生辐射。在运输过程中如果容器出现破损会对外界造成严重的后果,因此对屏蔽运输容器进行跌落和穿刺分析非常重要。本文通过spaceclaim软件建立屏蔽运输容器的三维模型,通过LS-DYNA软件对跌落和穿刺过程进行模拟,得到了屏蔽运输容器最大变形和应变,经分析当前设计能够对内容物进行有效的包容。Shielded transport containers can ensure the safety of radioactive waste transport. In China, high density polyethylene high integrity container (HDPE-HIC) as a new type of cargo package, there is no special shielded transport container, and a set of shielded transport container for HDPE-HIC is developed to prevent radiation to the outside world during the transfer and transportation of radioactive waste. If the container is damaged in the transportation process, it will cause serious consequences to the outside world, so it is very important to analyze the drop and puncture of the shielded transportation container. In this paper, spaceclaim software is used to establish a three-dimensional model of the shielded transport container, and LS-DYNA software is used to simulate the drop and puncture process, and the maximum deformation and strain of the shielded transport container are obtained. After analysis, the current design can effectively contain the contents.
