| 摘 要： | 应用计算机辅助设计和有限元网格划分的技巧和方法建立有限元模型,有效解决车体结构复杂和尺寸庞大的问题。分析双层集装箱车体受力状态,完成具有280万个自由度的超大规模有限元模型的集装箱车体强度计算。对两种装载方式下的集装箱车体试验测试结果和有限元计算分析进行了比较。结果表明,车体中间部位计算结果与试验结果比较吻合;而车体端部的计算结果大于试验结果,这是由于在实际制造时该位置处盖板孔的形状有所改善,因而有效缓解了原设计中该处存在的应力集中现象。

| Abstract: | With modern CAD method and smart skill of making mesh used, finite element (FE) model is established and the problem of complicated structure and large dimension is solved. The double stacked container body is analyzed with large-scale FE model which has 2 800 000 DOF, and the results from the tested and finite element analysis are compared. The test result shows that for the middle part of double stacked container, the stress results from the test and FE analysis are very close, but for the end part the result from FEA is larger than the tested. The reason is that the structure here has been modified so that the stress concentration has been reduced. |
