With the rapid development of large scale equipment to high speed, heavy load, high precision, high reliability, friction and vibration noise become more and more prominent, research on friction and vibration noise has become a new direction of tribology researches. Damping as an important aspect of the vibration noise and friction, there are still some scientific problems to be clarified, this study mainly focuses on material damping characteristics in friction and wear, manufacture materials with different damping characteristics, tribological behavior of different damping materials with different damping properties will be studied under sliding conditions, the mechanism of material damping in the friction and wear process of materials will be studied, the interaction and relationship between material damping property and friction behavior will be revealed, influence of friction process on the evolution of material damping behavior will be studied. finally a modified formula for material damping characteristics under sliding wear condition will be established, the relevant theoretical model will be established. This study can not only thoroughly understand the mechanism of material damping characteristics on the friction and wear mechanism, but also have practical significance for the preparation of antifriction and friction reducing materials from the aspect of material damping.

随着大型装备向高速、重载、高精度、高可靠性的快速发展，摩擦振动噪声问题日趋突出，摩擦振动噪声的研究已成为摩擦学研究的新兴方向，而材料阻尼特性作为影响界面摩擦振动噪声的一个重要方面，对其在摩擦磨损过程中的作用机理尚缺乏深入的认识。本项目针对摩擦磨损中材料阻尼特性的作用机理问题，运用不同阻尼材料阻尼机理差异性调控摩擦界面的阻尼特性，采用摩擦学研究方法，对滑动摩擦条件下各种不同阻尼性能的阻尼材料与阻尼特性相似的不同材料体系的摩擦学行为进行表征与研究，从而揭示材料阻尼特性在材料摩擦磨损过程中的作用机理，以及摩擦磨损过程中材料阻尼行为演变的规律；并建立考虑材料阻尼特性的滑动磨损条件下的磨损修正公式，完善理论模型。本研究不仅对深入认识摩擦磨损的基本规律有重要科学意义，也对从材料阻尼特性角度指导实际工程中的抗磨减摩有重要参考价值。
