Vulcanization was an important step in tire production process, directly determining the mechanical properties of the tire which was the most energy-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. Result showed that heat source temperature on the maximum temperature was the largest, effect of preheating temperature was the lowest; heat source temperature on the curing degree was the largest, effect of the curing time was lowest. According to the data analysis the optimal process parameters had been raised.
