摘要/Abstract

摘要： 纤维增强复合材料、高分子复合材料、三明治板等基础板件及其组合结构在城轨车辆中已经被广泛应用。由于其特有的性能和功能以及组合方案的多样性,在使用过程中往往很难判断和取舍。基于试验测试数据,重点分析了目前几种典型的单层复合材料板,玻璃纤维与碳纤维复合材料板,铝蜂窝、泡沫夹芯等三明治板及多种材料组合结构的隔声量,同时综合考虑了轻量化要求,提出了城轨车辆复合材料选择的基本建议,可为城轨车辆复合材料的选择提供参考。

Abstract: Fiber reinforced composites, polymer composites, sandwich panels and other basic panels and their combined structures have been widely used in urban rail vehicles. Due to their unique performance and function, as well as the diversity of the combination scheme, it is often difficult to judge whether to accept or reject during using process. Based on the experimental test data, the paper analyzes the sound insulation, such as several typical single-layer composite plates, glass fiber composite and carbon fiber composite plates, aluminum honeycomb, foam sandwich panels, and various material combinations. At the same time, a lightweight requirement is considered. Finally, the basic principles of composite selection of urban rail vehicles are proposed, which can provide reference for the selection of composite materials for urban rail vehicles.

Key words: rail vehicle, composite material, interior decoration, sound insulation
