Abstract
A multi-axis resonance fatigue test method and apparatus are provided by considering both stiffness coupling and inertia coupling in a resonance fatigue test that causes a complicated behavior and nonsymmetrical bending of a test article such as a wind turbine blade due to a coupling effect. In the method, a processor of the apparatus calculates a load value by considering a coupling between at least two axes of the test article. Also, the processor determines respective single-axis equivalent loads from the calculated load value by considering the coupling. This coupling may include at least one of a stiffness coupling and an inertia coupling.
