| Abstract: | In order to study the effect of piezoelectric friction damper’semi-active control,a new type of piezoelectric friction damper is designed based on the piezoelectric ceramic driver.Through the establishment of the space truss structure model and by using genetic algorithm,the optimal number and position of the damper are determined.Finally,the simulation experiment about semi-active control is done according to the model,obtaining that the model could gain the better control effect when decorating two dampers. |
