Abstract
Abstract. This paper outlines a novel segment test methodology for
wind turbine rotor blades. The segment test mainly aims at improving the
efficiency of the fatigue test as a future test method at Fraunhofer Institute for Wind Energy Systems (IWES).
While resulting in reduced testing times, target fatigue bending moments
over the intended test area have to be matched within an acceptable range of
overload. The numerical simulation reveals that the proposed segment testing
has a significant time savings of up to 43 % and 52 % for 60 and 90 m
blades. When compared to the experimental data of a 60 m full-length blade
fatigue test, the proposed methodology also shows better test quality over
the intended area and better certifiable regions over the outboard area.
