WebThe TTLCD exhibits the same natural frequency in all lateral directions, which is useful for wind turbines as they also exhibit nearly the same natural frequencies in fore-aft and side–side directions [45]. This indicates that the TTLCD can be tuned to control wind turbine vibrations in fore-aft and side–side directions simultaneously. • WebNov 7, 2024 · The toroidal tuned liquid column damper (TTLCD) is a recently developed device to mitigate multidirectional vibrations of structures. In this paper, a semi-active TTLCD (S-TTLCD), which can automatically identify the frequency change of structures and tune its natural frequency correctly by adjusting the liquid level, is proposed.
WebThe findings of the paper now clearly reveal that the TTLCD encompasses both an oscillatory liquid deflection as the first mode and a sloshing motion as the second mode vibration response. Accordingly, the results prove that the TTLCD operates not only multidirectionally but also as a unique multimodal device, ...
