Structural Control using Semi-Active Tuned Liquid Column Dampers

半主动控制系统由于其动力可调范围广、耗能小和内在稳定性好等特点 ,受到了普遍的关注。基于离复位控制 (OTE)算法 ,本文检验了一变阻尼半主动控制装置 -SATLCD的风振控制效果。本文的主要目标是研究OTE算法应用于SATLCD实施结构振动控制的可能性。数值研究确认了SATLCD的有效性和它相对于无控和被动控制的优越性 。

Semi-active control systems are becoming increasingly attractive for structural control applications due to their large adjustable capacity, low power demand and inherent stability. Based on the OTE algorithm, in this paper the semi-active tuned liquid damper (SATLCD) is employed for wind-induced vibration control. The main objective of this paper is to discuss the feasibility of using the SATLCD to exert structural control by applying OTE algorithm. The numerical result shows the effectiveness of the SATLCD and it's superior to the uncontrolled system and the TLCD, meanwhile, the rationality of the OTE algorithm is also verified.
