摘要

为研究海上柔直换流阀塔在海上运输过程中的强度及加固措施的有效性，依据某工程中的海上柔直换流阀塔建立有限元模型，结合自身振动特性研究换流阀塔在海上运输过程中的动力响应，分析了采取加固措施后的减振效果。结果表明，换流阀塔在连接前后两个单塔的弱轴方向顶部接线端子处出现较大位移，沿该方向采取加固措施后，同方向位移明显减小，各部位应力在满足安全要求的基础上进一步降低，加固措施效果明显。

Abstract

In order to study the strength and the effectiveness of reinforcement measure of offshore flexible direct current converter valve during marine transportation, a finite element model of offshore flexible direct converter valve was established, and the dynamic response of the converter valve during marine transportation was studied combining with its own vibration characteristics, and the vibration reduction effect after the reinforcement measures were analyzed. The results show that there is a large displacement at the top terminal of the weak axis direction of the two single towers before and after the connection of the converter valve. After the reinforcement measures are taken along this direction， the displacement in the same direction is significantly reduced, and the stress of each part is further reduced on the basis of meeting the safety requirements， and the reinforcement measures are effective.

Key words： offshore flexible direct current converter valve; finite element model; marine transportation; reinforcement measure
