摘要

以加成型液体硅橡胶材料的硫化反应动力学模型为基础计算了反应物系的转化率，推导了伴随硫化反应热的温度场基本控制方程，处理了常见的两类传热学边界条件，并详述了有限元模拟的实施步骤.进而设计了模具硅橡胶热硫化工艺的有限元模拟软件，并通过一典型算例及其硬度试验、工程应用实践验证了该模拟理论及算法的合理性.

Abstract

The kinetic model of vulcanization of liquid silicone rubber was established by experiment

and the conversion rate of the reactants was calculated. The fundamental control equation for calculating the temperature field accompanied by reaction heat was derived

and two types of thermal boundary conditions were analyzed. The implementation procedures of the numerical simulation were described in detail. The simulation software of hot vulcanization process of moldable silicone rubber was designed. Finally

the rationality of the simulation theory and algorithm was verified by one typical engineering example and its hardness test as well as its engineering application.
