Title:
TIRE RUBBER INDEX CALCULATING METHOD, DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/024877
Kind Code:
A1
Abstract:
Provided is a rubber index calculating device which calculates a tire rubber index with high accuracy. The rubber index calculating device (12) is such that a frictional energy measuring device (14) is made to measure tire frictional energy supplied to a tire under a plurality of tire input conditions, on the basis of the shear forces and slip amounts of the contact surface of the tire, that the frictional energy measuring device (14) is made to measure the frictional energy of a sample made of the same material as that of the tire, under sample input conditions which are set on the basis of the tire frictional energy measured under the aforementioned plurality of tire input conditions, that the measurement conditions for the sample wear amount are set on the basis of the tire frictional energy measured under the plurality of tire input conditions and on the basis of the sample frictional energy measured under the plurality of tire input conditions, that a wear amount measuring device (16) is made to measure the wear amount of the sample under the set measuring conditions, and that the tire rubber index is calculated on the basis of the sample frictional energy and wear amount which are measured.
