摘　　要：采用可模拟一维传热模型的模具,模拟轮胎硫化的内、外模温度,在无边界一维传热计算模型的基础上对双侧非等温传热模型任意一点达到某一温度所需要的时间进行定量的预测,预测值与实测值的相对误差绝对值小于5%。对2种规格载重轮胎的硫化时间最长处进行验证,结果表明,模型升温曲线、轮胎升温曲线、模具升温曲线基本吻合。本研究为实验室内一维传热模型的橡胶制品的硫化工艺优化提供了简便的方法。A mold capable of simulating a 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 temperature.The absolute value of 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 tires.The results showed that the heating curves of the model,tire,and mold were basically consistent.This study provided a simple method for optimizing the vulcanization process of rubber products within a one-dimensional heat transfer model in the laboratory.
