节能环保性能最强,但安全可靠性最弱的一种玻璃—真空玻璃的应用瓶颈问题是:真空玻璃是一种非安全玻璃。真空玻璃既要节能,也要安全。研究了真空玻璃结构优化设计及应用所涉及的力学基础理论。根据真空玻璃结构特点,建立力学模型,分析了真空玻璃在大气压作用下支撑应力分布特征及计算公式。综合真空玻璃应力分布特征及传热机理,优化真空玻璃结构,使真空玻璃达到最佳“热学与力学”配置,从而使真空玻璃在结构安全和节能环保两方面都达到要求。
The most energy-saving environmental protection, but the weakest safety and reliability of a glass - the application of vacuum glass bottleneck problem is: vacuum glass is a non-safety glass. Vacuum glass not only energy-saving, but also safe. The basic theory of mechanics involved in the optimization design and application of vacuum glass structure is studied. According to the characteristics of vacuum glass structure, a mechanical model is established, and the stress distribution characteristics and calculation formula of vacuum glass under atmospheric pressure are analyzed. Based on the stress distribution characteristics and heat transfer mechanism of vacuum glass, the vacuum glass structure is optimized so that the best “thermal and mechanical” configuration of the vacuum glass is achieved, so that the vacuum glass meets the requirements in structural safety and energy saving and environmental protection.
