摘要:

采用光弹法和动态法在线检测真空玻璃的真空度.试验测试表明,通过光弹仪可以观测到真空玻璃支撑物与玻璃支撑点处因应力集中而产生的应力光斑,而且随着真空度的提高,应力光斑直径也增大.同时,采用动态法测得的真空玻璃的固有频率也随着其真空度的增大而增大.对该两种方法的原理、检测过程及工程应用进行了分析,该两种方法特点是操作简单,结果直观可靠,易于实现真空玻璃实际工程在线检测.

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.
