Abstract

This article presents a methodology for the characterization of the dynamic properties of a laminated glass automotive ceiling, motivated by the inherent difficulty in obtaining laboratory samples from this kind of components. This methodology is based on the identification of the effective complex modulus of the laminated glass ceiling through Experimental Modal Analysis in conjunction with a finite element model. Besides, a material behaviour model is proposed for the effective complex module. Then, the dynamic properties of the laminated glass core are extracted from the latter using a reverse homogenized formulation of sandwich plates specifically developed in this work. As a result, a methodology to accurately predict the dynamic behaviour of these key automotive components has been achieved. An additional advantage of this methodology is that the identification of properties is carried out from a manufactured component and not from samples of reduced geometries, considering the impact of the manufacturing process.

汽车夹层玻璃天花板的动态特性表征

本文介绍了一种表征汽车夹层玻璃天花板动态特性的方法，这种方法的动机是由于从此类部件中获取实验室样本存在固有的困难。该方法的基础是通过实验模态分析和有限元模型确定夹层玻璃顶棚的有效复合模量。此外，还提出了有效复合模量的材料行为模型。然后，利用本研究中专门开发的夹层板反向均质化公式，从后者中提取夹层玻璃核心的动态特性。因此，准确预测这些关键汽车组件动态特性的方法得以实现。该方法的另一个优点是，考虑到制造过程的影响，属性识别是通过制造组件而不是缩小几何形状的样品来进行的。

期刊介绍： The Journal of the Spanish Ceramic and Glass Society publishes scientific articles and communications describing original research and reviews relating to ceramic materials and glasses. The main interests are on novel generic science and technology establishing the relationships between synthesis, processing microstructure and properties of materials. Papers may deal with ceramics and glasses included in any of the conventional categories: structural, functional, traditional, composites and cultural heritage. The main objective of the Journal of the Spanish Ceramic and Glass Society is to sustain a high standard research quality by means of appropriate reviewing procedures.
