| 利用ADINA软件对9.00R20和12.00R20规格斜平面及Y985规格圆锥面轮胎活络模具进行传热模拟分析，研究中套汽室改变对模具型腔温度分布的影响。结果表明：中套汽室的上端保持不变，底端上移使得中套汽室体积减小和中套下端强度提高；中套汽室体积减小可使轮胎模具型腔的平均温度降低0.2 ℃左右，并使稳态后模具型腔温度分布更均匀，有利于提高轮胎硫化质量，在一定程度上实现节能减排。 |
| 英文摘要: |
| The heat transfer of 9.00R20 and 12.00R20 inclined flat and Y985 conical segmented tire mold was simulated by ADINA software to study the effect of the change of the steam chamber of middle sleeve on the temperature distribution of the mold cavity.The upper end of the steam chamber of middle sleeve remained unchanged，and the bottom end moved upward，which reduced the volume of the steam chamber of middle sleeve and increased the strength of the lower end of middle sleeve.The average temperature of the mold cavity could be reduced by about 0.2 ℃ by reducing the volume of the steam chamber of middle sleeve，and the temperature distribution in the mold cavity under steady state was more uniform，which would be helpful to improve the vulcanization quality of tire，save energy,and reduce emission. |
