摘要
二阶波浪力和波浪压力对船舶和海洋工程结构物有着重要的作用,但这方面的实验资料目前还比较缺乏。为此,本文进行了测量一定吃水圆柱体在stokes波作用下的非线性绕射波浪压力和波浪力的模型实验。实验中成功地得到了二阶倍频压力和二阶倍频力,也得到了一些平均二阶压力的结果。实验结果显示了在高频时三阶波浪力大于二阶波浪力的现象。实验结果与文献的计算结果进行了对比。
Model tests have been conducted to measure the second order wave pressure and forces on a circular cylinder fixed in Stokes waves. The distribution of second order oscillating and steady wave pressure on the cylinder surface and the second order oscillating wave forces are obtained, but the steady wave force are not obtained due to its small amplitude. The experimental data also show that third order wave force may be greater than the second order one when the wave frequency is high and is therefore an important component of nonlinear wave force. The experimontal results are compared with the numerical results of second order wave pressure and force in the reference 〔3〕.
