Controlling beat phenomena in coupled systems using asymmetric tuned liquid column dampers
Research output: Contribution to specialist publication › Article
An investigation is made into controlling the natural frequency of tuned liquid column dampers (TLCDs) as a function of the geometry of the tank. A model is derived for free oscillations and the natural frequency is given as a function of the ratio of the vertical columns and the dimensions of the horizontal chamber. Asymmetric TLCDs are modelled in a structure-damper system. A numerical example demonstrates how the asymmetry of a TLCD affects beat phenomena exhibited in the decay of the structure.
