【摘要】 运动状态是阻尼体系最为基础的体现形式,从不同阻尼体系动力分析方法的基本区别入手,对不同阻尼体系的运动状态进行了基础性理论研究,得出了阻尼体系类别判定的充要条件,表明了体系运动状态连续是其为经典阻尼体系的直接决定因素。并以运动断层、鞭梢效应及半主动控制器加速度的"针尖"放大效应工程现象,讨论了各自阻尼体系的类别。更多还原

【Abstract】 Motion state is the most basic form of manifestation for a damping system. In terms of the basic differences of dynamic analysis approaches for different damping systems,a fundamental theoretical study was done for motion states of different damping systems to gain the necessary and sufficient conditions for their type identification. It was shown that the continuity of motion state is a direct and decisive factor to distinguish different classical damping systems. Three engineering phenomena including stick-slip motion,whiplash effect and acceleration amplification effect for a system with a semi-active controller were taken to discuss the type of each damping system.更多还原
