主动约束层阻尼振动控制技术现状及展望

A SURVEY ON VIBRATION DAMPING AND CONTROL USING ACTIVE CONSTRAINED LAYER DAMPING

本文在建模、控制策略、系统实现和应用等多方面对主动约束层阻尼振动控制技术的历史、现状进行了分析 ,指出了实施主动约束层阻尼振动控制技术继续发展的技术及待解决的问题。

It is proven that active constrained layer damping (ACLD) is valuable means for reducing vibration and improving the performance of a wide variety of engineering system. A brief overview and assessment of ACLD treatments employing viscoelastic materials and piezoactuator control strategies is presented in the paper. The concept, modeling, control strategies, system implementation, applications, and recent research developments of ACLD are provided.
