Beschreibung
Zusammenfassung:	The invention discloses an authentication test method for a large-size structure of a wind power blade. The method comprises a centering method of a test system, and construction and implementation of a static test and fatigue test system. The centering method is characterized in that a test system is built, the test system comprises a portal frame and an axial load loading system, the portal frame is composed of a foundation platform, stand columns, a lower triangular frame, an upper triangular frame and a cross beam, the axial load loading system is composed of a switching tool, a servo hydraulic cylinder, a force sensor, an upper hydraulic wedge-shaped clamp, a lower hydraulic wedge-shaped clamp and a base, and two optical axes form a centering target piece. The upper hydraulic wedge-shaped clamp and the lower hydraulic wedge-shaped clamp respectively clamp one optical axis, the lower hydraulic wedge-shaped clamp is fixed on the base, and the base is fixed after being debugged until no dislocation exists b
