Design method and system of tuned liquid damper

The invention belongs to the field of tuned liquid dampers, and provides a design method and system of a tuned liquid damper. The design method of the tuned liquid damper comprises the steps that the mass ratio of the tuned liquid damper is determined according to the vibration reduction requirement; the optimal tuning frequency ratio and the optimal damping ratio are calculated according to the relation among the mass ratio, the tuning frequency ratio and the damping ratio of the tuned liquid damper; determining model parameters of the tuned liquid damper according to the optimal tuning frequency ratio; determining a thickening agent concentration design scheme set according to the optimal damping ratio, and selecting any scheme from the thickening agent concentration design scheme set to obtain tuning frequency ratio test data and damping ratio test data of the corresponding tuned liquid damper model; and judging whether the current tuning frequency ratio test data and the current damping ratio test data ar
