本文介绍了“质量泵”的构造及工作原理,对具有“质量泵”的门式框架和剪切型多自由度体系的动力反应进行了分析,提出了在满足约束条件下,使反应方差最小来设计“质量泵”参数的方法。
This paper introduces the makeup of a mass pump and its working principle and analyses the dynamic responses of one degree and multidegrees of freedom systems with mass pumps. The methods of designing mass pump parameters are presented by making the response variances of structures be minimal under contrained conditions in this paper. An example of a single frame with a mass pumps under earthquake is given. and numerical results show that mass pumps esvices can contrcl the natural frequency of structures efficiently and reduce response amplitudes and increase structural dampings.
