摘要

以IEA-15 MW超大型单桩式风电机组为研究对象

基于几何精确梁理论的混合形式

建立包含叶片-机舱-塔架-基础的一体化非线性模型

探究其在风波联合作用下的动力特性。通过与开源软件OpenFAST计算结果的比较

验证所提出的一体化模型的准确性。结果表明

塔顶的位移响应受环境因素与运行状态的共同作用;气动荷载在结构的动力响应中占主导作用;由于波浪荷载与风荷载存在相位差

波浪对结构的动力响应可能有一定的抑制作用;塔顶处的加速度响应主要受其塔架一阶振型的影响

而塔架最大加速度响应出现在0.8倍塔架高度处

二阶振型对结构振动的影响也不能忽略。

Abstract

Taking one IEA-15 MW monopile wind turbine as an example

an integrated nonlinear model that considers blade-nacelle-tower-foundation interaction is established to investigate its dynamic characteristics under the combined actions of wind and waves based on the hybrid form of geometrically exact beam theory. The accuracy of the proposed numerical model is validated by comparing its calculation results with those of the open-source software OpenFAST. The results show that the displacement response at the top of the tower is affected by the combined effect of environmental conditions and the operating conditions. The aerodynamic loads play a dominant role in the dynamic response of the tower. The wave may have a certain inhibitory effect on the structural dynamic response due to the phase difference between the wind and wave loads. The acceleration response at the tower top is mainly influenced by the first vibration mode of the tower and the maximum acceleration response of the tower occurs at 0.8 times the tower height. The influence of the second-order vibration mode on the structural vibration cannot be ignored.
