| 目的 确定一种可抵御放射性物品C型货包撞击试验环境的内容器密封结构，为类似放射性物品运输容器的密封结构设计提供参考和依据。方法 开展C型货包内容器密封结构设计，利用数值分析方法确定一种可行的密封结构，通过撞击试验校验此密封结构的有效性。结果 货包在经历速度不小于90 m/s的箱顶角碰、箱顶正碰及箱体侧碰至刚性靶试验后，内容器的整体标准漏率均小于0.01 mPa•m3/s。结论 设计的密封结构可抵御冲击刚性靶速度不小于90 m/s的撞击试验环境，可对放射性物品进行有效防护。 |
| 英文摘要: |
| The work aims to affirm a type of container's sealing structure which can resist impacting test environment of radioactive material type C packages, so as to provide references and basis for sealing structural design of analogical radioactive material transport containers. The sealing structure of type C package's containers was designed, and a type of feasible sealing structure was determined by numerical analysis. The impacting test was completed to validate availability of such sealing structure. The integral standard leak rates of containers were all smaller than 0.01 mPa•m3/s after angled impact, top down impact and side impact onto an unyielding target at velocities not less than 90 m/s. The sealing structure designed can withstand the impacting test experiment whose impact unyielding target speed is not less than 90 m/s, and can protect radioactive materials effectively. |
