摘　　要：建立11.00R25轮胎硫化-传热耦合有限元模型,分别采用多维模型和混合定律模型模拟橡胶材料和橡胶-帘线复合材料,采用Isayev焦烧模型、经典内生热模型和混合动力学模型模拟橡胶的硫化特性,研究硫化介质温度对轮胎硫化特性的影响。结果表明,蒸汽温度对轮胎硫化影响较大,提出的分布区块法可以用来合理匹配蒸汽和过热水的温度。In this study, the coupled finite element models of curing kinetic and heat transfer of 11.00R25 tire were established. The models for rubber and rubber-cord composite material were simu- lated by multidimensional modeling and mixture modeling methods, respectively. The curing characteristics of rubber were simulated by using Isayev induction model, classical heat generation model and hybrid dynamic model. The effect of curing medium temperature on tire curing characteristics was then investigated by using the FEA models. The results showed that the steam temperature had significant influence on tire vulcanization. By using block method, the temperatures of steam and over-hot water were better distributed and matched.
