摘要
利用仿真分析软件Ansys Fluent和Workbench等对硫化胶囊内部流体域、胶囊内壁和轮胎进行仿真建模和热流耦合处理,分析硫化胶囊内部流体域平均压力、入口处流体域平均速度、内部液态水体积分数和流体域温度等的变化规律及自硫化机合模至硫化324 s内轮胎3个点位温度的变化规律。对比轮胎相应位置的仿真温度与实测温度曲线,验证了仿真模型的准确性,利用该模型可优化轮胎硫化工艺。
By using simulation analysis software Ansys Fluent and Workbench,the simulation modeling and heat-fluid coupling processing were carried out for the fluid domain in the vulcanization capsule,the inner wall of the vulcanization capsule and the tire,and the variation of the average pressure of the fluid domain in the vulcanization capsule,the average velocity of the fluid domain at the vulcanization capsule inlet,the volume fraction of the liquid water in the vulcanization capsule and the temperature of the fluid domain were analyzed,as well as the variation of the temperature at three points of the tire from the moment of mold closing to the vulcanization of 324 s.The accuracy of the simulation model was verified by comparing the simulated temperature curve and the measured temperature curve at the corresponding positions of the tire,and the tire vulcanization process could be optimized by using this model.
