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

摘要由于人类活动（如走路、跳跃和跳舞）引起的地板过度振动已经成为一些研究的主题。不幸的是，在找到解决这一问题的纠正措施方面只取得了有限的成功。本研究调查了磁流变（MR）装置（如MR阻尼器和TVA）在减少地板振动方面的有效性。将根据不同楼板系统的动态特性，制定设计这些装置的方法和准则。将在弗吉尼亚理工大学结构和材料研究实验室进行地板测试，并进行一系列动态测试，以对分析结果进行实验验证。几个行业将合作，并向项目主要研究人员提供技术和财政援助。本研究将由弗吉尼亚大学土木工程系、机械工程系和建筑系进行

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
