摘　　要：借助有限元分析软件对轮胎活络模具结构进行优化,收集模具优化前、后实际使用过程中升温趋势的试验数据,并对比分析预热及硫化过程中的传热性能差异;通过优化前、后模具硫化多个轮胎,分析所成型轮胎的硫化程度差异。结果表明:优化后模具在预热过程中的升温速率提高,生产初期成型的轮胎硫化程度较高,稳定生产阶段所成型轮胎的胎面硫化程度高于优化前模具成型的轮胎。Finite element analysis software was used to optimize the structure of the tire segment mould,the test data of the heating trend of the mould before and after optimization in the actual use were collected,and the difference of the heat transfer performance of the mould before and after optimization in the process of preheating and vulcanization was compared and analyzed.Multiple tires were vulcanized by the mould before and after optimization respectively,and the vulcanization degree of the tire was analyzed.The results showed that the temperature rise rate of the optimized mould increased during the preheating process,the vulcanization degree of tire moulded in the early stage of production was higher,and the vulcanization degree of the tire tread moulded in the stable production stage was higher than that of the mould before optimization.
