摘 要: 通过建立三维有限元实体模型来模拟轮胎的硫化工艺过程,分别研究了不同初温对轮胎硫化温度场及硫化程度的影响。研究表明,生胎的预热温度在不超过105℃时,其预热过程的硫化效应很小,且各点的硫化温度较均匀,因此预热处理使轮胎总的硫化程度趋于均匀。结果还表明,在105℃以下,预热温度每提高10℃,轮胎的机内硫化时间可缩短1.5min,若减少胶囊内通过热水的时间,其硫化均匀性可大大提高。 In this article, A 3-D finite element model has been developed to simulate the vulcanization process of tire and study how the deferent initial temperature affect vulcanization temperature field and extent of cure in tire. It was proved that the process time of vulcanization will shorten 1.5min accordingly when initial vulcanization temperature of tire be increased per 10℃(below 105℃) and at the same time, the homogenization of tire vulcanization state also be improved.
