| 摘 要： | 基于薄壁梁理论推导了总纵极限强度试验的相似模型设计应该满足的条件,然后选取小相似比尺满足某实验室的加载条件,分别设计出某集装箱船的双层模型和单层模型.通过对三段形式模型的非线性有限元分析,验证实船与模型的中拱、中垂极限强度的相似性.相对而言,总纵极限强度试验更适合选用单层模型.

| Abstract: | Based on the thin-walled beam theory, the relationship between the real ship and the similar model is derived, and then small scales are chosen to satisfy the loading conditions in one laboratory. One double-walled model and another single-walled model are designed for one container ship. Using the non-linear FEA, three-part models are calculated to validate the hogging-sagging ultimate strength similarity between the real ship and models. Relatively speaking, the single-walled model is more suitable for th... |
