摘　　要：给出了机敏约束阻尼概念，阐述了机敏约束层阻尼系统特征，分析了结构设计和系统建模方法。以典型梁系统为例，比较了被动约束阻尼技术和机敏约束层阻尼技术减振效果。结果表明；机敏约束层阻尼控制技术是一种更为有效的振动控制方法。最后，提出了今后重点研究问题。This paper described the concept and characteristics of smart constrained layerdamping and made an analysis on the design and modeling methods for this system. The effectiveness of vibration reduction was compared between passive constrained layer damping method andthis new method for a typical beam structure. The results show that smart constrained layerdamping is a more effective way for vibration control.The problems those should be studied in future are proposed in the last of the paper.
