- Abstract:
-
The vacuum degree of vacuum glass is detected online by photoelastic method and dynamic method. The experimental test shows that the stress spot caused by stress concentration at the vacuum glass support and the glass support point can be observed by the photoelastic instrument, and the diameter of the stress spot also increases with the increase of the vacuum degree. At the same time, the natural frequency of vacuum glass measured by dynamic method also increases with the increase of its vacuum degree. The principle, detection process and engineering application of the two methods are analyzed, which are characterized by simple operation, intuitive and reliable results, and easy to realize the online detection of vacuum glass actual engineering.
