Damping pendulum is an effeetive method to improve the stability of high-rise buildings.Based onthe dynamie analysis of the damping system, this study investigates the key factors and system parameterrelationships of damping pendulum, builds a damping device ,and quantitatively evaluates the actual dampingelfect and seismie resistanee through experiments, Research has shown that whether under periodie or nonperiodie exteral forces, the damping pendulum has an average damping ratio of 20% on the amplitude anddisplacement of the main oseillator vibration , signifieantly improving its seismie resistanee.And the reliability ofthe experiment was evaluated through uncertainty analysis.This artiele deeply analyzes the prineiple and devieeimplementation of damping pendulum damping from theory to praetice ,from qualitative to quantitative ,and hasteaching significanee for the deeply understanding and application of mechanical theory.
