大型海上风机吊装船是用于安装海上风机的特种船舶，其桩腿结构设计与强度分析对于保证船舶的安全运行至关重要。由于风机吊装船的桩腿为型钢材料，发生材料失效的形式包括材料屈服和薄壁件屈曲。本文首先介绍钢材的屈服强度和屈曲强度校核准则，然后介绍大型海上风机吊装船的桩腿结构，结合海浪动力学模型进行风电桩腿的载荷建模。最后，结合有限元计算软件Ansys-workbench进行了风机吊装船的桩腿强度分析和仿真。
Large offshore fan hoisting ship is a special ship used to install offshore fan. The design and strength analysis of its pile leg structure are very important to ensure the safe operation of the ship. Since the pile legs of the fan hoisting ship are shaped steel materials, the forms of material failure include material yield and buckling of thin-walled parts. This paper first introduces the checking criteria of steel yield strength and buckling strength, then introduces the pile leg structure of large offshore fan hoisting ship, and conducts load modeling of wind power pile legs combined with the wave dynamics model. Finally, the strength analysis and simulation of the pile leg of the fan hoisting ship are carried out by using the finite element calculation software ansys-workbench.
