Description

technical field [0001] The invention belongs to measuring instruments and equipment, and mainly relates to a measuring device for the ice on the surface of wind turbine blades and the adhesion strength between the wind turbine blades. Background technique [0002] At present, the research on the ice adhesion strength of the material surface mainly focuses on the plate-like structure. For the study of ice adhesion on the surface of flat structure, scientific and technological workers usually use three kinds of ice adhesion strength measuring devices: shear type, tension type and torsion type. However, the devices in the above three ways cannot bear and complete the test for the ice adhesion strength on the surface of the curved wind turbine blade. So far, there have been no reports on the research on the measurement device of ice adhesion strength on the surface of wind turbine blades at home and abroad. Contents of the invention [0003] The purpose of the present invent...
