摘　　要：用非线性有限元分析方法,建立了玻璃的热粘弹性应力松弛数学模型、Narayanaswamy结构松弛数学模型以及热边界模型,对平板玻璃钢化过程进行三维仿真模拟,得到玻璃中心和边界区域的温度与应力的变化历史及分布。为优化设计平板玻璃钢化参数提供了依据,能缩短产品开发周期、降低成本并保证产品质量。Three dimensional thermal tempering of glass plate has been simulated by using the non - linear FEM. Stress and structural relaxation numerical model for the simulation has been established by using the theory of thermo - viscoelasticity and Narayanaswamy ＇s structural relaxation of glass individually. Temperature and stress distribution and changes of glass plate are obtained, which will be useful for optimum designing and improving products quality.
