The main function of the TLD liquid damper for wind tower is to suppress the second order vibration of the tower, to reduce the second order vortex-induced vibration and fatigue damage of the tower. The TLD tuned liquid damper is mainly composed of three parts: the tank, the damper and the frame. It uses the dynamic side force generated by the liquid in the fixed tank during the shaking process to absorb the vibration. It has the advantages of simple structure, easy installation, good automatic activation, no required starter device, etc., and it has been widely used in wind tower vibration reduction.
