6 FAQs about [PS surface of wind turbine blade]

How many strain gauges are there in a wind turbine?

In the full-scale static testing, 56 strain gauges were attached to the surface of the wind turbine blade on the center of the pressure side (PS), the center of suction side (SS), the leading edge, and the trailing edge before testing. Thus, it is reasonable and effective to apply BPNNs in behavior and gesture studies related to VDTs.

Do wind turbine blades have structural bond lines?

Investigation of structural bond lines in wind turbine blades by sub-component tests Composite Structural Analysis of Flat-Back Shaped Blade for Multi-MW Class Wind Turbine Experimental investigation on ultimate strength and failure response of composite box beams used in wind turbine blades

Are wind turbine blades trailing edge buckling?

In recent years, many papers have reported the component level test technology of wind turbine blades, all of which aim to investigate the buckling failure of the trailing edge segment. For example, literature , introduces the test of blades trailing edge similar to this paper.

Do wind turbine blades need to pass static and fatigue tests?

Therefore, blades need to pass the static and fatigue tests specified in the IEC 61400-23 test rule in order to ensure the reliability of the blades in service. Then the tested blades can be mass-produced and installed on the wind tower for wind power generation.

How can torsional performance of blades be simulated?

The global failure of the blade can be simulated from the specified failure mode through subcomponent tests, so the previous studies can better observe the test process of the blade under a single working condition and study its stress response. In this paper, the torsional performance of blades is studied by the subcomponent test method.

Why do wind turbine blades increase in size?

The size of wind turbine blades increases gradually to reduce the manufacturing cost in fixed installed capacity. The significant blade manufacturing material is Glass Fiber Reinforced Plastic (GFRP), which has excellent tensile properties , , , .
