METHOD FOR TESTING THE RESISTANCE OF A TIRE TO A PRESSURE LOSS

摘要

The present invention relates to the tire pressure loss for test resistance to perforate, which is characterized in that described method includes following steps: creating the tire of multiple perforated walls by the way that multiple punching objects are passed through the wall; Making tire includes that perforation opposes roller to set a distance and controlled inflationary pressure; Stop rolling; And determination, for each perforation, index of resistance is based on from above-mentioned perforation the estimation leakage rate of the pressure loss; And because in the first stage, multiple punching objects include having taper smooth wall object, such as nail and the mode rolled carry out object and be not ejected at rolling; In second stage, multiple punching objects include a taper of object but include thread, such as screw rod and are rolled, in speed lower than 80 kilometers/hour.
