System Overview
● The blade static & fatigue test system is for performing static and fatigue tests of wind turbine blades, whose maximum span length is 66m.
● The static test system consists of five independent winches subjected to horizontal loads and one independent controller. ● The fatique test system consists of two actuators and one independent controller. The actuators operated by hydraulic power must be performed by one of the two actuating methods such as resonance excitation and direct load displacement, or combination of them. ● The fatique test must be capable of testing wind turbine blades to dual-axis direction as well as single-axis direction including flap-wise and edge-wise direction. ● The system's DAQ must have enough channels to simultaneously perform both static and fatigue tests, and be completely linked with the test controllers without any interfacing problem II.
