Experimental analysis of Tuned Liquid Damper （TLD） for high raised structures

Tuned liquid damper is one the passive structural control ways which has been used since mid 1980 decade for seismic control in civil engineering. This system is made of one or many tanks filled with fluid, mostly water that installed on top of the high raised structure and used to prevent structure vibration. In this article we will show how to make seismic table contain TLD system and analysis the result of using this system in our structure. Results imply that when frequency ratio approaches 1 this system can perform its best in both dissipate energy and increasing structural damping. And also results of these serial experiments are proved compatible with Hunzer linear theory behavior.

故障树方法在时间限制性派遣中的应用

时间限制性派遣(TLD)分析是飞机系统安全性分析的重要内容,其中一个重要环节是计算部件故障后的系统推力控制丧失率,目前采取较为保守的功能分析法进行分析,但其在复杂系统上的运用存在不足。为此,提出将故障树方法应用在TLD分析中。实例证明,故障树方法可用于任意复杂系统,结果更加精确,有助于提高TLD分析可操作性与精确度。
