Abstract:
      A mold that could simulate one-dimensional heat transfer model was used to simulate the internal and external mold temperatures of tire vulcanization.Based on the boundary-free one-dimensional heat transfer calculation model，a quantitative prediction was made on the time required for any point in the double-sided non-isothermal heat transfer model to reach a certain temperture.The relative error between the predicted and the measured values was less than 5%.Validation was conducted at the longest vulcanization time points of two specifications of truck and bus tire.The results showed that the mold，tire and mold temperature curves were basically consisent.This study provided convenient mothed for optimizing the vulcanization process of rubber products within a one-dimensional heat transfer model in the laboratory.
