摘要:

研究了利用磁流变阻尼器对巨-子型控制结构体系风振反应进行半主动控制的分析方法,建立了随机脉动风荷载下结构体系的振动控制方程,利用随机振动理论对脉动风荷载进行了计算机模拟,并采用基于经典最优控制理论的限界Hrovat最优半主动控制算法对结构体系风振反应的控制进行了研究.算例分析表明:采用磁流变阻尼器对巨～子型控制结构体系进行半主动控制后,主结构顶层的位移和加速度控制的减振率VAR分别为29.65%和68.09%,第2个子结构和第3个子结构顶层加速度控制的减振率VAR分别为40.18%和70.05%,有效地减小了结构体系的风振反应.

Abstract:

The analysis method of semi-active control of the wind vibration reaction of the giant-subtype control structure system using magnetorheological damper is studied, the vibration control equation of the structural system under random pulsating wind load is established, the computer simulation of the pulsating wind load is carried out by the random vibration theory, and the limited Hrovat optimal semi-active control algorithm based on the classical optimal control theory is used to study the control of the wind vibration reaction of the structural system. The analysis shows that after semi-active control of the giant~subtype control structure system by magnetorheological damper, the vibration damping rate VAR of the displacement and acceleration control at the top layer of the main structure is 29.65% and 68.09%, respectively, and the vibration damping rate VAR of the acceleration control of the second substructure and the top acceleration control of the third substructure is 2.3% and 40.18%, respectively, which effectively reduces the wind vibration reaction of the structural system.
