摘　　要：为了应对双船浮托安装风机时由于船舶运动导致的关键部件振动及应力问题,本文提出了一种针对风机安装过程中载荷转移的刚柔耦合多体动力学分析方法。通过建立双船浮托安装风机的刚柔耦合多体动力学模型,考虑了关键部件的弹性变形及其对系统整体的影响,对风机和基础的安装对接过程进行了动态分析。计算了不同工况下风机及关键部件的加速度和应力曲线,获得了动应力结果并研究了振动特性。研究表明,双船运动周期的变化会显著影响风机应力曲线的变化规律。这一研究为双船浮托安装风机系统的结构设计提供了理论基础,有助于提高安装过程的稳定性和安全性。In order to deal with the vibration and stress of key components caused by ship movement when installing wind turbines on double-ship float supports,this paper proposes a rigid-flexible coupling multi-body dynamics analysis method for load transfer during wind turbine installation.A rigid-flexible coupled multi-body dynamic model for the twin-barge float-over wind turbine installation was developed,considering the elastic deformation of key components and its impact on the overall system.Dynamic analysis of the installation and docking process of the wind turbine and foundation was performed,calculating acceleration and stress curves of the wind turbine and key components under various working conditions.The dynamic stress results and vibration characteristics were investigated,revealing that changes in the twin-barge motion period significantly affect the variation pattern of the wind turbines stress curve.This study provides a theoretical basis for the structural design of the twin-barge floatover wind turbine installation system,contributing to improved stability and safety during the installation process.
