DEVICE FOR MEASURING THE DYNAMIC DEFORMATION OF TIRE TREAD, CAPABLE OF MEASURING THE DEFORMATION OF THE READ BY IMAGE-PROCESSING

摘要

PURPOSE: A device for measuring the dynamic deformation of tire tread is provided to continuously photograph the deformation generated in each rubber block of the tread with a high-speed camera, thereby obtaining the deformation of the tread precisely by image-processing.;CONSTITUTION: A device for measuring the dynamic deformation of tire tread comprises a test road(1), basement(2), a tempered glass ground plate(3), and a high-speed camera(4). When a tire(101) of a vehicle(100) is driving on the tempered glass ground plate covering the opened top surface of the basement, the deformation of the tread is measured by continuously photographing the deformation of the tread with the high-speed camera. The tempered glass ground plate is possess-supported by a load support frame(5) installed in the basement, thereby being maintained at the height identical to the test road. Circular grooves(6) of identical size are continuously formed on the upper surface of the tempered glass ground plate. A plurality of color beads is contained inside the circular grooves. The upper surface of the tempered glass ground plate is covered with a black rubber sheet(8) of a high elongation ratio.;COPYRIGHT KIPO 2013
