DURABILITY TEST METHOD OF TRUCK-BUS TIRE BELT COMPOSITE

摘要

A method of evaluating durability of a tire belt part is provided to improve the measuring performance of the time within 24 hours by cutting the sample and mounting the sample at the fatigue tester. A method of evaluating durability of a tire belt part comprises a step of cutting/preparing a thread having upper and lower belt layers for a sample(3) with a predetermined specification; a step of fitting pins at the belt layers of the sample and preparing the deformation standard point; a step of mounting the sample at a fatigue tester and continuing the deformation with the predetermined period and time according to the use of the tire; and a step of measuring the crack displacement caused at the belt layers of the sample by considering the deformation angle of the pins fitted at the sample when applying the deformation or load to the sample.
