轮胎模具硫化过程数值模拟分析

Numerical Simulation Analysis of Vulcanization Process of Tire Mold

以12R22. 5轮胎硫化模具为例,采用ANSYS有限元分析软件,对模具在温模过程、开模过程和硫化过程的温度场进行仿真模拟,得到模具在3个过程中的温度分布、模具内取点温度-时间曲线、硫化过程的应力分布和型腔取点位置应力-时间曲线,可为模具结构改进提供参考。

Taking 12 R22.5 tire mold as an example,the temperature field of the mold was simulated during the mold heating process,mold opening process and curing process by ANSYS finite element analysis software. The temperature distribution of the mold during the three processes,temperature-time curves of specific points in mold cavity,stress distribution during the curing process and stress-time curves of specific points in mold cavity were obtained,which could provide a reference for mold structure modification.
