A Study of Nonlinear Magneto-Rheological Tuned Vibration Absorbers for Reducing Floor Vibrations

STUBY -OP St-MA 11-有源抗流变装置用于控制地板振动结构由于诸如行走、跳跃和跳舞等人类活动而引起的地板振动水平过高一直是几项研究的主题。不幸的是，只有有限的成功，在寻找纠正措施，这个problem.This study-investigated磁流变（MR）设备，如MR阻尼器的有效性，和TVA的减少地板振动。将根据不同地板系统的动态特性，为这些装置的设计制定方法和准则。将在弗吉尼亚理工大学结构和材料研究实验室进行地板试验，并进行一系列动态试验，以提供分析结果的实验验证。几个行业将合作，并为项目的主要研究人员提供技术和财政援助。这项研究将由弗吉尼亚州的土木工程、机械工程和建筑部门进行

A STUbY -OP St-MA11 -ACTIVE MAGNETO-RHEOLOGICALDEVICES FOR CONTROLLING FLOOR VIBRATIONSABSTRACTExcessive levels of floor vibrations due to human activities such as walkhg, jumping, and dancing have been the topic of several research studies. Unfortunately, there has only been a limited success in finding corrective measures to this problem.This study- investigates the effectiveness of magneto-rheological (MR) devices such as MR dampers, and TVA's for reducing floor vibrations. Methodologies and guidelines will be developed for the design of these devices based on the dynamic characteristics of different floor systems. A floor test will be constructed at the Virginia Tech Structures and Materials Research Laboratory and a series of dynamic tests will be performed to provide experimental verifications of the analvtical results.Several industries will cooperate and provide technical and financial assistance to the project principal investigators. This study will be performed by the Civil Engineering, Mechanical Engineering, and Architecture Departments of Virginia
