RIA: Analytical and Experimental Investigation of Active Mode Localization for Vibration Control in Structures

本研究项目提出了一种创新的主动模态定位方法，用于结构振动控制。该方法使用反馈来改变模态振型，使得那些非常微妙或关键的结构区域几乎感觉不到振动，而其他区域可能会有较大的振幅振动。瞬态和稳态振动都是可控的。这项研究工作包括分析开发和实验室演示，并强调了制造、空间、机器人和汽车工业中常见情况下的通用振动控制技术的阐述。＊＊＊

9410474 Clark An innovative active mode localization methodology is developed in this research project for structural vibration control. The approach uses feedback to alter the mode shapes such that those areas of structure which are very delicate or critical, sense little vibration, while other areas may vibrate at large amplitudes. Both transient and steady-state vibrations are controlled. This research work includes analytical development and laboratory demonstration, and emphasizes the elaboration of a general vibration control technique for commonly encountered situations in manufacturing, space, robotics and automotive industries. ***
