| Abstract: |
| This paper focuses on a better understanding of the beat phenomenon that maybe observed in the structural vibration control system using Circular Tuned Liquid Column Damper (CTLCD). The undamped control system, linearly damped structure with undamped CTLCD and damped control system are analyzed respectively to understand the beat phenomenon from a mathematical point of view. The results show that the response of the main structure cannot be suppressed with the appearance of beat phenomenon and even be magnified. The beat phenomenon on the free vibration of a structure can be disappeared for CTLCD with higher damping. The transient response of the structure can not be degraded promptly when beat phenomenon appears for forced vibration, so there would exist great errors if only the stead response of a structure is considered. |
