退火过程中超薄玻璃边部及板平面应力模拟研究
Simulation research of stress in edge and plate plane of ultra-thin glass during annealing
摘要
Abstract
The process of precision annealing can be affected by the special shape and thickness of ultra-thin glass edge.If the stress of this place is not be effectively modulate,there is a phenomenon of the plate glass is irregular and even crack when cutting the edge.Different shape and thickness of the edge of the plate glass with different thickness will be formed in the process of forming,which has different temperature and stress distribution in the edge and plate plane of ultra-thin glass during annealing. There exists a correspondence relationship between stress distribution and annealing conditions in the same edge and plate plane under different annealing conditions.The temperature field and stress field of ultra-thin glass plate under different annealing conditions are established by ANSYS.Analysis how the annealing condition affects permanent stress of ultra-thin glass and the relationship between them.This work provides a scientific theoretical basis and guidance for the stress control precision of ultra-thin glass during annealing process.关键词
