摘要
针对工程应用需要,研究设计一种质轻、高强度复合材料大阻尼的仪表板,提出使用共固化工艺制作新型嵌入阻尼的复合材料与PMI泡沫组合的多层夹芯结构,该结构能保持了复合材料优异的力学性能,又能达到减振、质轻的效果,并根据选用复合材料和铺层的不同提出了两种设计方案;通过有限元模型的计算分析初步表明:所提出方案能达到设计要求,结论可以为精密、高速、动载复合材料构件的设计提供参考。
According to the need of engineering,we designed an instrument panel with light weight,high strength composite damping. A multilayer sandwich structure with PMI foam combined with embedded and co-cured composite damping structure was proposed,which can maintain the excellent mechanical properties of composite materials,and achieve the damping and light effect at the same time. Two design schemes were proposed according to the different kinds of composite and layer. Through the calculation and analysis of finite element model,results show that the proposed scheme can reach the design requirements,and the conclusion can provide reference for the design of precision,high speed,dynamic composite components.
