全钢子午线轮胎活络模具的传热模拟分析

Heat Transfer Simulation on Segmented Mould for All-steel Radial Tire

以12.00R20全钢载重子午线轮胎活络模具为例,利用有限元模拟软件分析模具的传热过程,并根据模拟结果优化模具结构设计。弓形座结构改进后,花纹块的上下温差由1.2℃降为0.9℃,使花纹块的温度分布更趋于均匀,有利于轮胎硫化质量的提高。

Taking all-steel radial tire segmented mould for example, heat transfer process of the mould was analyzed by using finite element simulation software, and the mould structure was optimized according to the simulation results. After the structure of bow-shape seat in mould was modified,the temperature field on pattern segment was more uniform. The temperature difference between upper and lower point of the pattern segment decreased from 1.2 ℃ to 0.9 ℃. The tire vulcanization quality was improved after the modification.
