Active Vibration Control of Engineering Structures Using Air Jet Pulses
(Konya Technical University, 2019) Hızarcı, Berkan; Kiral, Zeki
Research and development of structural response control systems are animportant area of interest for researchers. Under the different static anddynamic loads, it has become a necessity to use structural control systems inorder to reduce the vibration response of engineering structures. Seriousefforts have been made to transform the structural response control conceptinto a viable technology. Innovative active vibration control systems are neededto improve the structural dynamic behavior of structures used in differentoperating environments or operational processes. In this regard, the idea ofreducing the vibrations of structures using air jet pulses remains to beinvestigated and implemented. In this study, the response patterns of the samplestructure and vibration control via air jet pulses under harmonic baseexcitation were examined. Harmonic base excitation was given around the firstnatural frequency at which the structure has the highest displacement.State-feedback control method was used for vibration control of the structure.The forces required for vibration control of the sample structure were calculated.In addition, with the help of Matlab Simscape Multibody, physical modeling ofthe system and visualization of the vibration were provided. The results werecompared and it was observed that the vibration of the structure can be dampedvia proposed system. Finally, the nozzle design was conducted to providecontrol forces with air jet impulses to the system.
