Damage Evaluation in Tempered Vacuum Glazing via Multivariate Statistical Methods

The performance of tempered vacuum glazing (TVG) strongly depends on the structural parameters and degree damage products. In this paper, attention was paid to six indicators which had a major influence TVG, new evaluation were derived from them using principal component analysis (PCA). particular, hierarchical clustering (HCA) based Euclidean distance measurement enabled TVG products be classified into three kinds. Considering results PCA, product quality classification established according damage. method proposed in work found simple reliable provide references for detection TVG.
