摘要/Abstract

摘要： 采用混合定律模型来描述橡胶-钢丝复合材料的比热容、导热系数随温度的变化规律,利用K-R动力学模型来分析硫化反应热,基于非线性有限元软件ABAQUS编制了相应用户子程序,实现了轮胎硫化过程一体化模拟分析.在此基础上,以11.00R22.5型全钢载重子午线轮胎为研究对象进行了硫化过程模拟分析,并与轮胎硫化测温试验以及传统的模拟分析结果进行了对比.结果表明:利用此模拟分析方法可以有效地提高轮胎硫化分析精度.进而分析了硫化过程中轮胎内部温度、焦烧时间和硫化程度的变化情况,确定了轮胎的最难硫化部位,为轮胎硫化工艺设计提供了理论指导.

Abstract: The specific heat and thermal conductivity of rubber-steel composite materials were described using a mixing rule model proposed by the authors. The K-R kinetics model was used to calculate the curing reaction heat. The user subroutine was compiled based on nonlinear finite element software ABAQUS and the integration simulation of tire vulcanization process was achieved. Then the curing process of radial tire 11.00R22.5 was simulated by this analytical method. Simulation result was compared with experiment result and with the results obtained by other researchers. The accuracy and applicability of the proposed method was confirmed by the comparison. Finally, the variations of the temperature, induction time and the curing-state were analyzed during the curing process. The last curing point of the tire was found. These findings can provide theoretical guidance for the design of tire curing process.

Key words: highway transportation, tire curing, curing kinetics, user subroutine, state-of-cure, induction time
