成型辅鼓直径对轮胎耐久性能的影响

基于Abaqus软件，对275/65R17轮胎进行有限元分析，研究成型辅鼓直径（D′）对轮胎耐久性能的影响。结果表明：当D′变化时，轮胎带束层拉伸率、带束层角度、带束层密度、胎体拉伸率和冠带层拉伸率均发生变化；随着D′的减小，轮胎各部位应力和温度先降低后升高，当D′为726.76 mm时轮胎整体应力和温度最低，轮胎耐久性能最好。;Based on Abaqus software，the finite element analysis of 275/65R17 tire was carried out to study the effect of the diameter of building auxiliary 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 decreased 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
