Effect of Surface Finish of Braced Pillars on Stress Distribution of Vacuum Plate Glass

Abstract:

Article Preview

The braced pillars were machined by grinding and spark machining. 3-D topography and surface roughness of two kinds of braced pillars were measured. The effect of two kinds of braced pillars on stress distribution of vacuum plate glass was analyzed by electrometric method, and was in comparison. The stress distribution of their important sides was obtained such as sealing side, supporting side and braced pillar. The experimental result showed that maximal stress of braced pillar for vacuum glass occurred in the end side of each braced pillar. Controlling 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.
