摘　　要：采用ANSYS软件对 10 .0 0R2 0型子午线轮胎构建三维有限元实体模型 ,模拟轮胎的硫化工艺过程 ,定量分析了不同预热温度对轮胎硫化温度场及硫化程度场的影响 .结果表明 ,预热温度每提高 10℃ ,胶囊内通过热水的时间可缩短 2min ;机内硫化时间缩短 1min ;硫化均匀性相对提高 10 % .预热温度越高 ,轮胎的机内硫化时间越短 ,硫化均匀性越好 ;综合考虑预热过程的硫化效应因素 ,得到轮胎硫化前的最佳预热温度不宜超过 10 5℃ .A 3-D finite element model was established by using ANSYS to simulate the vulcanization process of 10.00R20-type radial tire. The effects of different preheating temperatures on the temperature field and extent field of tire vulcanization were then quantitatively analyzed. The results show that the flowing time of heated water in capsulae shortens by 2min and the vulcanization time in curing machine shortens by 1 min with an initial vulcanization temperature increasing of 10℃. At the same time, the homogeneousness of tire vulcanization state improves by 10%. The results also shown that higher preheating temperature will result in shorter tire curing time in curing machine and better vulcanization homogeneousness. By synthetically considering all the factors influencing the vulcanization in preheating process, it is concluded that the optimum preheating temperature is not more than 105℃.
