新燃料元件运输容器使用了多种非金属材料来实现减振、防火等功能。本文利用ANSYS/LS-DYNA程序进行运输容器1.2 m自由下落试验的有限元分析。首先,根据材料力学试验数据确定金属材料以及非金属材料的材料模型和材料常数。其次,建立规模恰当的有限元模型,设置接触边界条件,确定适用于非金属材料的沙漏参数。最终,完成多种跌落角度自由下落试验的有限元分析,确定1.2 m自由下落试验的试验方案。计算结果表明,设计的新燃料元件运输容器满足美国机械工程师协会(ASME)规范BPVC-III的强度要求。
New fuel components transport containers use a variety of non-metallic materials to achieve vibration, fire and other functions. In this paper, ANSYS / LS-DYNA program was used to carry out the finite element analysis of 1.2 m free-fall test of transport container. First, the material model and material constants of metallic and non-metallic materials are determined based on the material mechanics test data. Secondly, the appropriate size of the finite element model is established, the contact boundary conditions are set, and the hourglass parameters suitable for non-metallic materials are determined. Finally, a complete finite element analysis of a variety of drop-free drop test to determine the 1.2 m free-fall test program. The calculation results show that the new fuel cell transport container designed meets the strength requirements of the American Society of Mechanical Engineers (ASME) Code BPVC-III.
