| 目的 根据容器特点提出栓系方法，在栓系系统建立、受力分析以及结构优化等有限元使用方面给出建议，为放射性物品运输的力学安全评价提供参考。方法 根据不同运输容器的栓系方式特点，将栓系系统分为4类:栓系绳栓系、支座固定栓系、运输格架栓系以及挤压约束栓系。采用组合加速度因子作为载荷条件，选取代表性栓系结构进行有限元分析，给出运输容器、栓系组件的受力特点和危险区域。结果 对放射性物品运输活动中的栓系系统进行了总结和归纳，针对不同栓系方式提出改进方案。结论 力学分析结果具有包络性，4类栓系方式能够适应大部分运输容器在道路、铁路以及水路条件下的运输要求，为放射性物品运输栓系系统设计和安全评价提供了参考。 |
| 英文摘要: |
| The work aims to put forward the retention system according to the package characteristics and give suggestions on the establishment of retention system, stress analysis and structural optimization, so as to provide reference for the mechanical safety evaluation of radioactive material transport. According to the retention characteristics of the different transport packages, the retention systems were classified into four categories:tie, baseplate, framework and array. The finite element analysis was conducted to the typical retention systems under the combined acceleration factor load condition, to obtain stress characteristics and danger zones of the packages and retention members. The retention systems in the transportation of radioactive materials were summarized, and the improvement schemes were proposed according to different retention methods. The mechanical analysis results are enveloping, and the four types of retention methods can meet the transportation requirements of most transport packages under the conditions of roads, railways and waterways, which provides a reference for the design and safety evaluation of the retention system for radioactive material transport. |
