摘要/Abstract

摘要： 为设计出隔声性能优异的轨道交通等运输工具用复合材料,本文采用热压罐工艺制备复合材料夹芯结构层压板,通过对铺层结构、厚度以及阻尼层进行设计有效调控复合结构隔声性能。结果表明:厚度和密度的增加可以有效提高复合材料的隔声性能;阻尼层的使用使得复合结构内部界面处阻抗匹配失调;声波在界面处极易发生反射,声能消耗增多有效提高了复合材料的隔声性能;利用结构优化设计可以在降低复合材料质量的情况下,提高隔声性能,最终满足复合层合结构材料在高端运输领域的隔声需求。

Abstract: In order to design a kind of composite material with excellent sound insulation performance for rail vehicles and other transportation vehicles, the autoclave process was employed to prepare this composite material with a sandwich structure laminates. Performance of sound insulation of this composite structure was effectively controlled with a design of the laminated structure, thickness and damping layer. The results show that the sound insulation performance can be effectively improved with an increase in thickness and density of composite materials. The utilization of a damping layer makes the impedance mismatch at the internal interface of the composite structure, which results in that the sound waves are easily reflected at the interface, and the increase in sound energy further step consumption effectively improves the sound insulation performance either. With the structural design, the weight of the composite material was not only reduced but the sound insulation performance was improved. Finally, it makes this composite laminated structure material meet the sound insulation requirements of the high-end transportation field.

Key words: rail transit vehicle, composite laminates, sound insulation, structural optimization
