Fatigue Strength and Fatigue Test of Drive Train Components
Fatigue strength and life cycle are two key elements in the design of a wind turbine, guaranteeing a safe operation and high availability of the product. The increasing power output of wind turbines and the often accompanying up-scaling processes show new and unexpected effects. The utilization of large testing facilities allows to verify prevailing design processes of large components, increase the safety of the dimensioning and to make weight savings possible. Theoretical models for component dimensioning and processes for accelerated life cycle tests can be improved or validated and findings can be transferred to other components; the research project "BeBen XXL" is one example, scrutinizing the main bearings of wind turbines.
