A wireless measuring device and method for surface icing adhesion force

Abstract

The present disclosure provides a wireless measurement device and method for surface icing adhesion, which relates to the field of adhesion detection, and includes a test piece attached to the test area, and the side of the test piece away from the test area is provided with multiple sets of Strain gauges, multiple sets of strain gauges are arranged at intervals around the periphery of the test piece for obtaining surface stress changes of the test piece; the strain gauges are electrically connected to the controller, and the controller obtains strain gauge data through the measurement module for use in It is sent to the external display terminal for display through wireless communication. By setting strain gauges on the peripheral parts of the test piece, the problem of the uncertainty of the freezing position and thickness of the blade during the rotation process is solved, and the measurement data is combined with wireless transmission. The stress change on the surface of the blade is measured and observed in real time, which provides sufficient data reference for studying the icing situation on the blade surface.

Description

technical field [0001] The present disclosure relates to the field of adhesion detection, in particular to a wireless measurement device and method for surface ice adhesion. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] As the climate changes, the problem of icing on wind turbine blades has attracted more and more attention. In order to solve the related problems caused by icing of wind turbine blades, it is necessary to conduct anti-icing experiments on the blades; in the anti-icing experiments of blades, the The measurement of the important parameter of adhesion is particularly important. However, the development of related measurement schemes and theoretical research on adhesion is slow, and it is difficult to meet the needs of solving the problem of blade icing. [0004] The inventors found that the current measurement methods for...
