Abstract
Bu çalışmada, akillı bir kirişin titreşim özelliklerinin piezoelektrik yamalann algilayıcı olarak kullanılmasıyla elde edilmesi incelenmiştir. Akillı kiriş, darbe çekici veya piezoelektrik yama ile uyarılmış ve sistemin frekans cevapları algilayıcı olarak kullanılan piezoelektrik yama yardımıyla elde edilmiştir. Piezoelektrik algilaycıların yerinin sistemin frekans cevapları üzerindeki etkisi ise akıllı kiriş üzerinde farklı piezoelektrik yama seçimi ile incelenmişir. Sonuçlar piezoelektrik yamanın algilayıcı performansını test etmek amacıyla teorik, tek eksenli bir ivmeölçer ve lazer yardırmıyla yer degiştirme ölçüm cihazından elde edilen veriler ile de karşılaştırılmıştır.
In this study, vibration characteristics of a smart beam are investigated by using piezoelectric patches as sensors. Smart beam is excited by either impact hammer or piezoelectric patch and the frequency response of the system to these excitations are obtained from a piezoelectric patch used as sensor. The effect of the location of the piezoelectric sensor on frequency response of the system is also presented by choosing different piezoelectric patches along the smart beam. In order to investigate the performance of the piezoelectric patch in sensing, all results are then compared to those obtained from theory, single-axis accelerometer and laser displacement sensor.
