扁平轮胎硫化工艺温度参数的确定

硫化是轮胎生产工艺的一个重要步骤,直接决定轮胎的力学性能,是生产中耗能最多的一个环节。传统的扁平轮胎硫化工艺没有考虑后硫化的作用,这可能造成能源的浪费。前期的有限元模拟表明传统的硫化工艺造成了大部分胶料的过硫化。为了找到改进硫化工艺的方法,本文研究了硫化参数对胶料温度场和硫化程度场的影响。硫化参数包括热源温度、硫化时间和预热温度。相对应这三个因素,用ABAQUS有限元软件建立三维模型做了三组对比模拟,结果表明对温度场影响最大的是热源温度,最低的是预热温度；对硫化程度影响最大的是热源温度,最低的是硫化时间。根据数据分析提出了最优的工艺参数。

Determination of Temperature Parameters on Flat Tire Vulcanization

vulcanization was an important step in tire production process, directly determining the mechanical properties of the tire whichwas the mostSenergy-intensive link. The traditional vulcanization process of a flat tire did not consider the post curing effect, which may result in a waste of energy. Early finite element simulation showed that the traditional process caused excessive vulcanization. In order to find ways to improve the curing process, in the paper effect of process parameters on the flat tire vulcanization had been studied. Curing parameters included heating temperature, curing time and preheating temperature. Corresponding to these three factors, the three-dimensional model was established by ABAQUS finite element software to carry out three groups of simulation. Results showed that effect of heat source temperature on the maximum temperature was the largest, preheating temperature was the lowest; effect of heat source temperature on the curing degree was the largest, the curing time was lowest. According to the data analysis the optimal process parameters had been raised.
