摘　　要：杂交阻尼控制技术是许多工程结构减振和改善性能的重要方法之一.本文主要从杂交阻尼结构的几个特征方面:阻尼结构形式、建模假设、黏弹性材料建模、响应分析方法、控制方法、参数研究和结构选择来研究杂交阻尼结构的研究进展和主要研究成果.研究发现绝大多数的文献只局限于研究梁板的问题.因此很有必要加强对壳体等复杂结构的研究.最后文中指出了有关杂交阻尼结构继续发展的有待深入研究的几个方面。It is verified that hybrid damping is effective in suppressing vibration and improving the performance of a wide variety of engineering structures. Based on several key features of hybrid damping structures, including damping configurations, modeling assumptions, viscoelastic material modeling, response analysis methods, control strategies, parametric studies and types of structures, recent advances in hybrid damping structures and main contributions are presented in this paper. It is found that most of the contributions are concerned with beams and plates only. Therefore, more research efforts are needed for complex shell structures such as cylinders, cones. Finally, several issues for future research in hybrid damping structures are outlined.
