摘　　要：压电材料是一类重要的功能材料,具有将机械能和电能相互转化的压电效应,受到阻尼减振领域学者的广泛关注。概述了近年来利用压电效应控制结构振动和制备阻尼材料方面的研究成果。利用压电效应能够对结构振动进行有效的主动和主被动控制。与结构振动控制相比,利用压电效应制备阻尼材料还是一个年轻的领域。已有的研究表明,利用压电效应能够提高材料的阻尼性能。但仍有许多问题需要进一步研究,如界面相互作用对材料功能性质和力学性质的影响、提高压电材料产生的电能向热能转化的效率的方法、材料的阻尼性能与组成结构的关系等。Piezoelectric material is a kind of important functional materials, by which the energy transformation between mechanical energy and electric energy can be realized. In this paper, the research results of structure vibration control and damping material preparation by making use of material piezoelectricity in recent years are described. Utilizing piezoelectricity, the structure vibration can be effectively controlled by active or passive method. In contrast to structure vibration control, utilizing the property of piezoelectricity to prepare damping materials is a new area. It is noticed that the use of piezoelectricity can improve the damping performance of materials, but there are so many problems needed to be solved by further investigation, such as the effect of interfacial interaction on functional and mechanical properties of materials, method of enhancing the efficiency of transforming electric energy (produced by piezoelectricity) to heat energy, the relationship between composition and damping performance of materials, etc.
