| 英文摘要: |
| As a critical component of offshore wind turbine operation and maintenance, the study of wind loads during hoisting operations is
of paramount importance. Among these, three-blade hoisting, as a commonly employed method, warrants in-depth investigation into its wind
load characteristics during operation. To enhance offshore hoisting operations and mitigate risks, this study establishes a rotor hoisting
model, conducting theoretical analysis and derivation of wind loads on the hoisting system across various construction phases, including the
horizontal lifting stage, blade rotation stage, and vertical lifting stage. Based on airfoil theory and using the NREL-5MW turbine as a case
study, a computational program was developed to calculate wind loads during three-blade hoisting operations. The analysis examines the
influence of wind attack angles, wind direction, and elevation on wind loads during hoisting, assessing safety and reliability to provide
practical engineering references and guidance. |
