Problems solved by technology
[0006] 1) The above measurement methods are all aimed at the static ice layer formed on the surface of the material, but there is no corresponding measurement for the tensile adhesion strength of the dynamic ice layer formed on the material surface;
[0007] 2) The size of the adhesion is related to the shape and size of the material, so the above measurement method cannot accurately represent the tensile adhesion strength of the ice layer on the surface of the material;

The invention discloses a device for measuring the tensile adhesion strength of a dynamic ice layer on the surface of a material, the device comprises a working platform, a cup base, a gas core and a flexible carrier, the gas core is fixed on the working platform, and a first gas channel pipeline communicated with the gas core is arranged in the working platform; the cup base is detachably arranged on the air core in a sleeving manner, and a second air path pipeline which is communicated with the air core and penetrates through the upper surface of the cup base is arranged in the cup base; and the flexible carrier covers the outlet of the second air channel pipeline. The cup base of the measuring device can be replaced with different materials so as to measure the tensile adhesion strength of dynamic ice on the surfaces of different materials. The measuring device is loaded through air flow and a flexible carrier, and the phenomenon of interface stress concentration can be relieved or avoided, so that the tensile adhesion strength of the interface can be measured more truly and accurately. Correspondingly, the invention also provides a method for measuring the tensile adhesion strength of the dynamic ice layer on the surface of the material.
Description
technical field [0001] The invention belongs to the technical field of ice layer interface mechanical performance measurement, and in particular relates to a measurement device and a measurement method for the tensile adhesion strength between a dynamic ice layer and a surface of a base material. Background technique [0002] Surface icing and frosting refer to a phenomenon of ice aggregation and adhesion caused by water solidification or water vapor condensation in a low temperature environment (or icing environment). For example, frost on automobile glass, icing on power transmission equipment; icing on aircraft wings, icing on refrigeration facilities and air conditioners, etc. The icing phenomenon on the material surface is not only affected by the important factor of temperature, the surface characteristics of the icing surface, especially the surface energy, the adhesion of the surface to the ice and the hydrophobicity of the surface have a great influence on the icing...
