摘要
为了降低放射性物质在运输与贮存中出现泄漏的风险,通常采用抗事故包装箱对其进行包装防护。介绍了抗事故包装箱跌落的数学模型和缓冲材料的力学性能,基于能量转化的思想分析了抗事故包装箱端面跌落、底面跌落和角跌落三种典型情况,给出了端面跌落和底面跌落时缓冲层厚度的计算公式,并对角跌落时缓冲层厚度是否满足设计要求的验证方法进行了分析,给出了有效的验证方法。计算方法和公式可为抗事故包装箱工程结构初步设计提供理论依据。
In order to reduce transport and storage of radioactive substances in the risk of leakage occurring, occident-resistant packaging container is usually applied for protection.A math model of acci- dent-resistant packaging container and the mechanical properties of buffer materials are introduced as well. Based on the conversation of energy,three typical drop conditions,including end drop,bottom drop,and corner drop ,are analyzed,and a computation formula for buffering thickness during end dropping and bot- tom dropping is provided.In addition the method for verifying whether the buffering thickness in corner dropping satisfies the design requirement is analyzed to provide an efficient verifying method.In one word the computing method and formula provide a theoretical basis for primary design of the engineering struc- ture of accident-resistant packing container.
