摘要

由于分段模型试验可模拟船体的弹性效应，而模型龙骨梁模拟实船刚度分布的准确性对该试验能否模拟真实物理现象至关重要。介绍已有的龙骨梁模型，提出更能反映甲板大开口船舶结构的槽型龙骨梁模型；介绍槽型龙骨梁应力测量方法，并实验验证该方法的可行性。以某船型为例介绍槽型龙骨梁的设计流程，并基于迁移矩阵法计算进行验证。

Abstract

Segmented model experiments are the most real and effective method of researching wave loads, which simulates the elastic effect of the hull effectively. Since the backbone model simulates the stiffness of real ship truly is essential, which directly determines whether the segmented model experiment simulates the real physical phenomena or not. The existing keel girder models domestic and foreign were reviewed. A channel-section keel girder was proposed which better simulates the hull structure with large opening in deck. The method of stress measurement was introduced and viability was proved by test. The process of designing channel-section girder was introduced with an example, at last validation of the results was made based on migration matrix method.
