HAVA JET İTKİLERİ KULLANARAK MÜHENDİSLİK YAPILARININ AKTİF TİTREŞİM KONTROLÜ

Research and development of structural response control systems are an important area of interest for researchers. Under the different static and dynamic loads, it has become a necessity to use structural control systems in order to reduce the vibration response of engineering structures. Serious efforts have been made to transform the structural response control concept into a viable technology. Innovative active vibration control systems are needed to improve the structural dynamic behavior of structures used in different operating environments or operational processes. In this regard, the idea of reducing the vibrations of structures using air jet pulses remains to be investigated and implemented. In this study, the response patterns of the sample structure and vibration control via air jet pulses under harmonic base excitation were examined. Harmonic base excitation was given around the first natural 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 of the system and visualization of the vibration were provided. The results were compared and it was observed that the vibration of the structure can be damped via proposed system. Finally, the nozzle design was conducted to provide control forces with air jet impulses to the system.
