| Abstract: |
| Based on Abaqus software，the finite element analysis of 275/65R17 tire was carried out to study the effect of the diameter of auxiliary building drum（D′ ） on the tire durability. The results showed that，when D′ changed，the tensile rate of the belt layer，angle of the belt layer，density of the belt layer，tensile rate of the carcass and tensile rate of the crown belt layer all changed. With the decrease of D′ ，the stress and temperature of each part of the tire first decreased and then increased. When D′ was 726. 76 mm，the stress and temperature of the whole tire were the lowest，and the tire durability was the best. |
