中文摘要:

为研究垂荡板对传统Spar平台水动力特性的影响，以Umaine-Hywind Spar平台为模型，利用有限元软件对垂荡板在Spar平台不同位置处的频域和时域特性进行分析，并在最佳位置处对比分析了不同透空率的垂荡板对Spar平台影响。结果表明：在相同的海况条件下，垂荡板在Spar平台下部安放有利于其工作，使其获得的响应更小，而在下部安放的垂荡板中，透空率为5%的垂荡板性能优于透空率为0的垂荡板。综合几个算例可以得出：垂荡板可以改变并优化Spar平台，然而这需要考虑影响垂荡板的因素（透空率，板间距、数目等），并非垂荡板就一定会降低Spar平台的垂荡响应。

英文摘要:

In order to study the influence of heave plate on hydrodynamic characteristics of traditional spar platform,the paper took Umaine-Hywind Spar platform as a model,and used finite element software to analyze the frequency domain and time-domain characteristics of heave plate at different locations of Spar platform and the influence of heave plate with different opening rates on Spar platform at the best location.The result showed that under the same sea condition,the best location is that heave plate is placed in the lower part of Spar platform,which make the response be smaller, the property of heave plate in opening rate of 5% is better than that of 0% under the same sea condition.The result showed that heave plate can vary and optimize Spar platform.However,the influence factors such as opening ratio, spacing and numbers of plate etc on heave plate should be considered.Heave plates will uncertainly reduce the heave response of Spar platform.
