中文摘要:
      采用有限元分析方法研究23.5R25全钢工程机械子午线轮胎的硫化过程。结果表明：轮胎各部位模拟硫化温度曲线与实测硫化温度曲线的升温趋势接近，最大误差不大于10%，模拟方法可行；同一时刻轮胎各部位温度存在显著差别，其硫化程度不同，物理性能不能同时达到最优；轮胎各部位的硫化历程差别较大，胎肩部位初始硫化速度缓慢，降温速度也较缓慢滞后，存在后硫化现象；降温硫化对轮胎硫化程度影响较大。
英文摘要:
      The vulcanization process of 23.5R25 all-steel off-the-road radial tire was studied by finite element analysis.The results showed that the temperature rising trends of the simulated vulcanization temperature curve and the measured vulcanization temperature curve were close，and the maximum error was not more than 10%，which indicated that the simulation method was feasible.At the same time，each part of the tire had significant temperature difference，and their vulcanization degree were different，so the physical properties could not reach the optimum at the same time.The vulcanization process of each part of the tire was quite different.The initial vulcanization speed at the tire shoulder was slow，and the temperature reduction speed was also slow and lagged behind.There was a post vulcanization phenomenon.The temperature reduction vulcanization had great influence on the vulcanization degree of tire.
