针对传统阻尼器抗振控制效果不佳的缺陷，提出了一种简单谱激励下大跨度结构主动调频质量阻尼器抗振控制方法。建立了主动调谐质量阻尼器的抗振矩阵，计算了振动矢量位移，设计了矩阵变换表达式，计算了振动响应值，分析了振动响应对抗振位移的影响，实现了主动调谐质量阻尼器的稳定协调控制。通过对比实验验证了该方法在实际应用中可以提高阻尼器的抗振控制幅度。
Aiming at the defect that the traditional damper has little anti-vibration control effect, an active frequency-modulated mass damper anti-vibration control method for large-span buildings under simple spectrum excitation was proposed. The anti-vibration matrix of active Tuned mass damper was established, the vibration vector displacement was calculated, the matrix transformation expression was designed, the vibration response value was calculated, the effect of vibration response on anti-vibration displacement was analyzed, then the stability and coordination control of active tuned mass damper were realized. A comparative experiment was presented to verify that the proposed method could increase the amplitude of anti-vibration control of the damper in the application.
