Multifunctional test platform and test method for wind turbine blade

The invention discloses a multifunctional test platform and test method for a wind turbine blade, and belongs to the technical field of wind turbine blade test. The test platform comprises a host unit, a loading frame, a vertical actuator, a horizontal actuator, an iron floor platform, a three-legged support, a stand column adjusting device, a clamping tool, a clamping base, a hydraulic unit, a hydraulic substation, a hydraulic pipeline, a controller and a computer software unit. The test platform realizes the targeted test of the structure and defect influence of a certain specified structure area of the blade; the test platform is designed into a horizontal type and a vertical type, so that the test result is prevented from being influenced by deformation caused by the gravity of a test piece, and meanwhile, different loading postures can also meet the requirements of various test characteristics. The testing method comprises structural testing and static and dynamic experimental testing, and can specifical
