Abstract: The purpose of this work is to establish a computational system to numerically estimate the fatigue life of a 5MW wind turbine blade under wind loads. A one-way partitioned fluid-structure interaction (FSI) coupling strategy is adopted, where two highly parallelized codes, FrontFlow/blue (FFB) and ADVENTURE_Solid, are used to account for the aerodynamic effects applied on the blade surface and the structural response of the blade, respectively. The fatigue damage rate distribution of the whole blade can be estimated by recourse to an empirical method implemented in ADVENTURE_Fatigue. This fatigue evaluation method involves the rain-flow counting algorithm, the Goodman’s diagram and Miner’s accumulation law. Finally, we perform a numerical example to demonstrate the capacity of the established computational system in structural and fatigue analysis of the 5MW wind turbine blade under wind loads.
