Problems solved by technology

[0003] With the increase of wind power blades, in the actual test process, the lateral horizontal loading technology will have insufficient space in the height direction, resulting in the problem that the test wind power blades touch the ground and cannot be tested
At the same time, during the actual test, it was found that with the increase of wind power blades, the lateral horizontal loading technology is likely to affect the static test results, resulting in inaccurate static test results

Abstract

The invention provides a wind power blade static structure test device and test method, and relates to the technical field of static structure test. The wind power blade static structure test device comprises a bearing platform, and at least one loading mechanism arranged along a preset direction and used for supporting and fixing a blade root part of a wind power blade; and the bearing table is configured to enable the blade tip part of the wind power blade in the preset direction to be higher than the blade root part; so that preset included angle is formed between the connecting line of the blade tip part and the blade root part and the horizontal plane, the loading mechanism is used for applying loading force to the wind power blade, and the loading force is the same as the gravity direction of the wind power blade and the clamp. When the static structure test device for the wind power blade is used for testing the static structure of the wind power blade, the test cost and the loading difficulty of the wind power blade are reduced, and meanwhile, the accuracy of the static test is effectively improved.

Description

technical field [0001] The present application relates to the technical field of static structural testing, and in particular, to a static structural testing device and testing method for wind turbine blades. Background technique [0002] Such as figure 1 as well as figure 2 , the existing wind power blade structure static loading mechanism adopts lateral horizontal loading technology, the wind power blade 20 is installed horizontally on the bearing platform 11, and a loading member 135 is installed on one side of the bearing platform 11, and the pulling force generated by the loading member 135 is located above it. The guide wheel 133 turns the traction force into a horizontal loading force, and loads the wind turbine blade 20, which is called a lateral horizontal loading technique. [0003] With the increase of wind power blades, in the actual test process, the lateral horizontal loading technology will have insufficient space in the height direction, resulting in the p...
