TIRE GROUNDING SHAPE ANALYSIS DEVICE AND TIRE GROUNDING SHAPE ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To provide a tire grounding shape analysis device that can accurately analyze kinetic grounding property of a tire in a short time, and to provide a tire grounding shape analysis method.;SOLUTION: A tire grounding shape analysis device includes: a lighting unit for irradiating a grounding surface of a tire, which is an analysis object, with light for increasing luminance of an edge of a groove provided in a tire tread part; a grounding surface image acquisition unit 32 for acquiring a captured image of the grounding surface of the tire using light radiated by the lighting unit; and a grounding property analysis unit 33 for analyzing a grounding surface image acquired by the grounding surface image acquisition unit 32 to obtain a grounding property.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2020,JPO&INPIT
