调谐液柱阻尼器参数计算的简化方法
|
摘要
建筑振动是结构工程中遇到的主要问题之一,如何减震已经成为该领域的研究热点。大量的理论实践证明,调谐液柱阻尼器(tuned liquid column damper,TLCD)是一个能有效减震的装置,并且由于其结构简单,易于安装,已经越来越多的在实际工程中得到应用。TLCD对建筑物减震效果的好坏,取决于其自身的参数,参数的选择至关重要。但是,由于液体固有的非线性阻尼特性,如采用传统的迭代法来计算参数,需要大量的时间用于计算,本文针对这个问题,提出了一种简化计算方法,以便能更方便地得出TLCD最优化的减震参数,进而方便设计合适的阻尼器。
Building vibration is one of the main questions in the structural engineering,how to control the vibration has become the main concern of researchers.It has been proved by many theories that the tuned liquid column damper(TLCD) is an efficient device to damper the vibration and can be installed conveniently due to its simple structure.It has been applied more widely in engineering.The choice of the parameters is the most important which influences the performance of the TLCD.However,a great deal of computational effort is required to search the optimum parameters of TLCD with the traditional iteration method due to inherent nonlinear liquid damping.In order to simplify the calculation,a closed form solution scheme is proposed to obtain the optimum parameters more conveniently,and then to design TLCD more easily.
