摘　　要：试验研究带束层帘线直径及压延密度对轮胎耐久性能的影响。结果表明,在其他条件相同的情况下,直径大且密度高的帘线对轮胎的耐久及高速性能产生负面影响。选用带束层帘线时,确定帘布总强度后还应考虑帘线直径和压延密度,避免压延密度过高,可通过提高帘线的强度级别达到高破断力指标;使用大直径钢丝帘线,应适当增大帘布的压延厚度,并减小帘线压延密度,以保证轮胎的耐久性能,提高轮胎的使用寿命。The effect of belt cord diameter and calendering density on the endurance of tire was investigated. The results showed that large diameter and high density cords had a negative impact on the endurance and high speed performance of tire. Therefore the belt cord diameter and calendering density should be considered after the total strength of cord was determined during the selection of belt cords, and high calendering density should be avoided. High breaking force could be achieved by increasing the strength level of the cord. When large diameter steel cords were used, it was recommended to increase the calendering thickness of steel cord and reduce the cord density to ensure the endurance of tire and improve the service life of tire.
