Effect of Surface Topography on Stress Distribution of Vacuum Plate Glass for Different Aluminum Alloy Braced pillars

摘要：

The effect of different surface topography on stress distribution of vacuum plate glass for the aluminum alloy braced pillars was analyzed by electrometric method. The results show that the maximum stress exists at the interfaces of all experimental glasses sheet and the top and bottom sides of a brace. The conclusion that the size of contact area between braced pillar and glass has an impact on stress distribution of the glass is obtained. The stress-strain field of different vacuum plate glasses was analyzed by the finite element method. The stress distribution of their important sides was obtained such as sealing side, supporting side and braced pillar. The experimental results are shown that high precision of the brace height and good flatness of the glass sheet considerably improve vacuum plate glass quality，such as its strength，its dependability and service life.
