Structure Vibration Control System Based On The Isolation And Passive Damping

With a variety of architectural form complex and frequent earthquake disasters in recent years, The disadvantage of traditional seismic methods have been shown. A number of scholars at- home and abroad do research on a variety of structural vibration control technique.According to the theory basis.the model design and simulation test based on two structural vibration control technique are researched. The layout of the paper is as follows:The first chapter is the introduction. in this part, a various of earthquake disaster at home and abroad in recent years are introduced; the significance of structure vibration control and development is put forward. This paper introduces the principle of a variety of vibration control method and their application scope.It introduces their research progress and application in practical engineering and analyses the disadvantage of each method, and then puts forward the research direction and research content.The second chapter introduces the principles of structure vibration isolation and the four isolation methods. And mainly introduces the structure of base isolation. The structure vibration control model based on base isolation is designed according to the principle of vibration isolation. The vibration control system are processed and experiment.The same Jane harmonic and Seismic waves were input to the system under the isolation and no isolation two states. Acquisite vibration acceleration of the structure and then map the acceleration-time curve. Compare the two cases of acceleration-time curves. Result shows that the isolation vibration control effect is very significant.The third chapter introduces the principles of tuning damper and common tuned damper methods. At the same time introduces the application examples of various kinds of tuned damper methods. Mainly introduced the principle of TMD, PTMD vibration control. The structure vibration control model based on base isolation is designed according to the principle of TMD and PTMD. The vibration control system are processed and experiment.The same harmonic waves and Jane harmonic were input to the system under the no control and the TMD,PTMD three states. Acquisite vibration acceleration of the structure and then map the acceleration-time curve. Compare the three cases of acceleration-time curves. Results show that the effect of the structure vibration control based on TMD, PTMD is obvious,energy Energy consumption faster based on PTMD,it has more significant effect.
