Fatigue life prediction of wind turbine rotor blades manufactured from composites

摘要: Abstract: Blades of modern wind turbines, which are commonly fabricated composites, play an important role in capturing the kinematic energy flow. The random nature flow renders these blades as fatigue critical elements. They exposed to different loads during their lifetime and they expected sustain mission for at least 20 years. Therefore, reliable damage progress models need be developed. Due applied loading patterns, investigation using stochastic simulation is inevitable. Furthermore, should capable considering various material properties. Prior establishment proper models, accurate characterization load cases a vital task.
