Title:
METHOD OF EVALUATING TIRE GROUND CONTACT CHARACTERISTIC
Document Type and Number:
WIPO Patent Application WO/2018/139411
Kind Code:
A1
Abstract:
This method of evaluating a tire ground contact characteristic comprises: placing a tire on one surface of a flat plate; loading the tire with a prescribed load, or setting the tire to an unloaded state; irradiating the tire with terahertz waves having a frequency of between 0.1 THz and 10 THz, from the other surface side of the flat plate or from within the flat plate, where the wavelength of the terahertz wave is greater than a roughness average length of at least a portion of said one surface of the flat plate, and/or greater than a roughness average height of at least a portion of said one surface of the flat plate; detecting a reflected terahertz wave from the tire; and evaluating the characteristic during ground contact of the tire on the basis of the result of the detection.
