Abstract

The invention belongs to the technical field of intelligent manufacturing, and particularly relates to a preparation method of a composite conductive polymer flexible sensing array. The method provided by the invention comprises the steps of adding tetrahydro-(4R)-carboxy-(2S)-phenylthiazole, (7aR)-3-phenyl-1H, 3H-imidazo [1, 5-c] thiazole-(6, 7aH)-5, 7-dione, polyvinylpyrrolidone, polyvinylidenefluoride, polylactic acid, polypyrrole and polythiophene into tetrahydrofuran, and heating in an autoclave to obtain sensing ink; and screen-printing a sensing ink array pattern on the surface of a nylon fabric, and drying in a hot press to obtain the composite conductive polymer flexible sensing array. The composite conductive polymer flexible sensing array is used as a gasket and clamped betweenan inner ring and an outer ring of an aviation knuckle bearing, and the sensing sensitivity of the flexible sensing array to stress strain, temperature and humidity is 7.9-9.3, minus 2.16* 10<-3>- minus 1.92* 10<-3> K<-1> and 937%-998% respectively on an aviation bearing testing machine.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and specifically relates to a preparation method of a composite conductive polymer flexible sensing array. Background technique [0002] Joint bearing is a kind of spherical sliding bearing. Its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during motion. method made. Joint bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, and good lubrication. The allowable working temperature of spherical plain bearings is mainly determined by the matching materials between the sliding surfaces of the bearings, especially the plastic material sliding surfaces of self-lubricating spherical plain bearings, and its load-carrying capacity will tend to decline at high temperatures. If the sliding surface material of the lubricated joint bear...
