摘要
塔架是海上风机的重要组成部分,由于风机的重力、风载荷和波浪载荷的影响,塔架将弯曲变形。在深海海域复杂的波浪载荷和风载荷下,塔架的振动特性有待深入研究。本文首先模拟了不同风速和不同波长下塔架的振动位移变化情况,在风速和波高一定时塔架切向和拍向的最大振动位移随着波长呈现一种不同的趋势;通过水池试验测量了对应工况下的风机塔架振动值,并与数值模拟结果进行了比对。研究结论为实际海上风机平台工作环境的选择提供了一定的参考。
The tower is an important part of the wind turbine platform.Due to the gravity,wind load and wave load of the wind turbine platform,the tower will bend and deform.Under the complex wave load in the deep sea,the vibration characteristics of the tower need to be further studied.In this paper,firstly,the vibration displacement of the tower under different wind speeds and different wavelengths is simulated.When the wind speed and wave height are fixed,the maximum vibration displacement of the tower in tangential direction and beat direction presents a different trend with the wavelength;through the pool test,the vibration value of the wind turbine tower under the corresponding working conditions is measured and compared with the numerical simulation results.The research results provide a certain reference for the selection of working environment of offshore wind turbine platform.
