摘  要:综合考虑轮胎不同部件胶料的氧气消耗和气体扩散过程,建立轮胎充气压力损失有限元分析模型,研究轮胎内衬层胶配方、内衬层结构、充气介质及充气压力对轮胎充气压力损失率(IPLR)的影响。结果表明:考虑胶料氧气消耗可以有效提升轮胎充气压力损失有限元分析模型的预测精度;内衬层胶配方和充气介质氮气/氧气体积比对轮胎IPLR影响明显;内衬层厚度与轮胎IPLR之间存在近似线性关系;充气压力对轮胎IPLR影响较小。In this study,the oxygen gas consumption and gas diffusion process of the compounds of different tire parts were analyzed,the finite element analysis model of tire inflation pressure loss was established,and the effects of the tire inner liner compound formula,inner liner structure,inflation medium and inflation pressure on the tire inflation pressure loss rate(IPLR)were studied.The results showed that the prediction accuracy of the finite element analysis model of tire inflation pressure loss could be effectively improved by considering the oxygen gas consumption of the compounds.The inner liner compound formula and the inflation medium nitrogen/oxygen volume ratio had obvious effects on the tire IPLR,there was an approximately linear relationship between the inner liner thickness and the tire IPLR,and the inflation pressure had little effect on the tire IPLR.
