Stress Characteristics in Offshore Wind Turbine Rotor Hoisting Based on Numerical Simulation
摘要
Abstract
To study the stress characteristics during the hoisting process of offshore wind turbine rotors,a three-dimensional rotor hoisting numerical model is established using ABAQUS,and a numerical simulation study is conducted for the entire process of gradually rotating the rotor from a horizontal lifting state to a vertical state.The results indicate that:(a)the peak stress of the blade shell is 2.75 to 3.42 times that of the internal web,making it more prone to deformation during hoisting;(b)under horizontal lifting conditions,significant stress concentration occurs at the main lifting point of the hub and the root of blade,with the stress at the hub's main lifting point being 2.25 times the peak stress of blade;and(c)as the rotor transitions from horizontal lifting to vertical lifting,the stress on the blades gradually decreases,while the stress on the hub gradually increases.These findings can provide technical supports for the safety control of offshore wind turbine rotor hoisting operations.关键词
