摘要
研究组合载荷下海上风机塔架的受力特性。基于江苏启东海域6 MW海上风机资料,采用GH Bladed软件开展组合载荷下海上风机塔架的受力特性数值模拟,得到以下主要结论:与风载荷作用相比,在风载荷+波浪载荷组合作用下,风机塔架基础底面所受峰值剪力提升72.0%,峰值弯矩提升8.3%;波浪载荷对基础所受剪力和弯矩的影响显著,在相对波高为4时,基础底面所受相对剪力和相对弯矩分别为3.04和1.44;与风载荷作用相比,在风载荷+地震载荷组合作用下,风机塔架基础底面所受峰值剪力提升76%,峰值弯矩提升21%。研究成果可为启东海域海上风机设计及施工提供理论支撑。
The mechanical characteristics of the offshore wind turbine tower under combined loads are studied.Based on the data of 6 MW offshore wind turbine in Qidong sea area of Jiangsu Province,GH Bladed software is used to carry out the numerical simulations on the mechanical characteristics of the offshore wind turbine tower under combined loads.The main conclusions are as follows:the peak shear force on the bottom of the wind turbine tower under combined loads caused by the wind and wave increases by 72.0%and the peak bending moment by 8.3%compared with those under the wind load;the wave load is of a significant effect on both the shear force and bending moment on the bottom of the wind turbine tower,when the relative wave height is 4,the relative shear force and the relative bending moment on the bottom of the wind turbine tower are 3.04 and 1.44,respectively;the peak shear force on the bottom of the wind turbine tower under the combined loads caused by the wind and earthquake increases by 76%and the peak bending moment by 21%compared with those under the wind load.The research results can provide theoretical support for the design and construction of offshore wind turbines.
