The single blade installation method for large-scale offshore wind turbine has the advantage of reduced deck and crane requirements on the installation vessel. Accurately simulating the coupled dynamic responses of the system throughout the entire hoisting process is crucial to avoid spatial interference with surrounding structures. Additionally, the aerodynamic loads, particularly the turbulent wind with spatiotemporal non-uniformity, further aggravate the uncertainty of the dynamic responses. Therefore, a numerical model capable of comprehensive analysis of mechanical-hydrodynamic-aerodynamic-control is urgently needed. However, it is challenging for the commercial software to achieve the coupling analysis. In this paper, the hoisting process is investigated by jack-up installation vessel, so the influence of wave loads on the structure is not considered. The aerodynamic loads are firstly calculated by the blade element theory, and then the numerical model is established by the Lagrangian method, finally the analysis program is developed in MATLAB. The accuracy of the program is verified by code-to-code, and the interaction between the ship-mounted crane and aerodynamic loads during the hoisting process are analyzed. The results show that the aerodynamic loads should be considered during the hoisting of the blade, and the established program could determine the trajectory of the blade inputting the sea state, which can avoid the possible collisions with the surrounding structures.

大型海上风电机组单叶片安装方式的优点是减少了安装船的甲板和吊机要求。准确模拟整个吊装过程中系统的耦合动态响应对于避免与周围结构的空间干扰至关重要。此外，气动载荷，特别是具有时空不均匀性的湍流风，进一步加剧了动态响应的不确定性。因此，迫切需要一种能够综合分析机械-流体动力-气动-控制的数值模型。然而，商业软件实现耦合分析具有挑战性。本文采用自升式安装船研究吊装过程，不考虑波浪载荷对结构的影响。首先利用叶片单元理论计算气动载荷，然后利用拉格朗日法建立数值模型，最后在MATLAB中开发分析程序。通过代码对代码验证了程序的准确性，并分析了船装起重机在吊装过程中与气动载荷的相互作用。结果表明，叶片吊装过程中应考虑气动载荷，所建立的程序可以确定叶片输入海况时的运动轨迹，避免与周围结构可能发生的碰撞。
