摘要(Abstract):

机械系统在使用过程中的振动会产生噪声且缩短设备的使用寿命,开发减振降噪复合材料是当前研究的重要内容。从复合材料微观、宏观多尺度的方向解析复合材料模型的模态性能研究为出发点,进而讨论了当前三维纺织结构对复合材料的阻尼性能的贡献,为研究新一代复合材料的模态性能做理论与技术指导。
The vibration of mechanical system will produce noise and shorten the service life of equipment.The development of vibration and noise reduction composite materials is an important content of current research.Starting from the research of modal performance of composite model from the micro and macro multi-scale,the contribution of 3D textile structure to damping performance of composite is discussed,which provides theoretical and technical guidance for the research of modal performance of a new generation of composite.
