As new-style, non-light tight and insulated material of the 21st century the vacuum glass head the list of successful candidates by virtue of excellent resistance to ageing, thermal retardation, permeation of visible light and reflection of infrared light. The vacuum plate glass was systematically researched, which played a tremendous role in future field of saving energy reducing loss. Researching on stress of the vacuum glass under external action of natural environment is the main research work today. This research on the vacuum glass in the process of actual operation had some practical value, which had some social and economic value on research and promotion of the vacuum glass in our country.This article made systematic, detailed theoretical research and experimental study on the vacuum plate glass in the condition of wind load. Specific supporting structure of the vacuum plate glass was researched on supporting stress field. Meantime, Maximal and minimal stress points of the vacuum flat glass were triumphantly tested on the different conditions of wind load. Researching on stress of structural support had significant meaning to optimizing structural support of the vacuum plate glass, increasing strength, increasing reliability and service life.(1) This article simulated actual work environment of the vacuum plate glass. The conclusion that supporting stress of the vacuum plate glass was changed by external wind velocity was obtained. Important evidence was provided for establishing environmental parameters of test standards of materials.(2) Matlab software was used in programming. Under the procedure presentation, the wind pressure received by the vacuum glass was obtained through inputting parameters of wind pressure calculation of the vacuum plate glass.(3)Adopting the node method and single, multi-ply trigonometric series method to establish mathematical model of stress distribution of the vacuum plate glass(4)This article analyzed the mathematical model by the finite element method. Deformation field of stress of the whole vacuum glass was analyzed by ANSYS. The colored pictures of accurate stress distribution were obtained. Stress distribution of the important side is immediately expressed such as sealing side, supporting side and supporting pole, and the basic coincident result of the theories calculation and the software analysis were obtained.
