MASTER TIRE ASSEMBLY, AND CREATION METHOD OF FUNDAMENTAL DATA AND CALIBRATION METHOD OF UNIFORMITY MEASURING APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a calibration technology of a uniformity measuring apparatus according to an absolute evaluation method.SOLUTION: A master tire assembly 10 including an inner diameter ring 20, an outer diameter ring 40, and a tire part 60 corresponds to a prototype for calibration. The inner diameter ring 20 and outer diameter ring 40 are obtained by machining a metal, so that the dimensional accuracy is high. A uniformity measuring apparatus can be calibrated using the master tire assembly 10. An absolute evaluation can be performed using the master tire assembly 10, so that the present invention provides a calibration technology of the uniformity measuring apparatus according to an absolute evaluation method.
