摘要
放射性物质货包力学试验是证明货包结构设计安全性的重要试验之一。货包力学试验通常是一种破坏性试验,为得到对货包损坏最大的下落取向,通过预先计算分析确定货包下落取向成为目前国际上使用较多的方法。本工作采用ANSYS/LS-DYNA有限元分析软件,对货包的力学试验进行仿真分析。通过对计算结果分析,得到货包最大损坏的下落取向及应变和加速度数值,并与试验结果进行了比较。
Mechanical test for transport package of radioactive material is one of the important tests for demonstrating package structure design.Drop test of package is a kind of destructive test.It is a common method of adopting the pre-analysis to determine drop orientation.Mechanical test of a sealed source package was calculated with finite element method（FEM） software.Based on the analysis of the calculation results,some values were obtained such as the stress,strain,acceleration and the drop orientation which causes the most severe damage,and the calculation results were compared with the results of test.
