Abstract

ABSTRACT This research proposes a new approach, in which a tuned mass damper (TMD) is installed in an articulated tower subjected to moving loads caused by ground. Then, the vibration equations of the system are formulated for analyzing and selecting the optimal parameters of the tuned mass damper to reduce the harmful vibrations. The maximization of equivalent viscous resistance method is applied to determine the optimum parameters of the tuned mass damper. The purpose of designing the tuned mass damper is to suppress the vibrations of the articulated tower. The results show that the vibration of the articulated tower is effectively eliminated by using the optimum parameters of the tuned mass damper in this paper. In particular, the optimum expressions are given in analytical solutions, which involve the parameters in well-understood forms to derive the exact solution of the optimum parameter. These optimum expressions, helping the researchers easily design the tuned mass damper on controlling vibrations of the articulated tower.

具有调谐质量阻尼器的铰接塔在地面加速度惯性力作用下的振动控制
摘要本研究提出了一种新的方法,将调谐质量阻尼器(TMD)安装在承受地面移动荷载的铰接塔中。然后,建立了系统的振动方程,用于分析和选择调谐质量阻尼器的最佳参数,以减少有害振动。采用等效粘性阻力最大化法确定调谐质量阻尼器的最佳参数。调谐质量阻尼器的设计目的是抑制铰接塔的振动。结果表明,采用调谐质量阻尼器的优化参数,可以有效地消除铰接塔的振动。特别地,在解析解中给出了最优表达式,该表达式涉及以众所周知的形式存在的参数,以导出最优参数的精确解。这些优化表达式有助于研究人员轻松设计用于控制铰接塔振动的调谐质量阻尼器。
