二阶波浪力数值计算与试验方法研究

The investigation of wave drift force model test

目前准确测量波浪中船舶与海洋结构物二阶波浪力是一个难点,本文提出采用半约束法和弹簧系统约束法两种试验方法测量二阶波浪力.首先介绍了半约束法和弹簧系统约束法两种试验方法,然后针对某散货船采用这两种方法开展了二阶平均波浪力试验测量研究,最后将试验结果与理论计算结果进行了对比,并对两种试验方法的优缺点进行了分析.研究结果表明:两种试验方法均能准确测量二阶平均波浪力.

Aimed to wave drift force measurement of model test, two schemes test have been carried out in seakeeping basin. The model test result matched well with the numerical simulation. The advantage and disadvantage of two test schemes were present.The results show that two test method can be used to measure wave drift force.
