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.展开更多
