Yapısal Sağlık İzlemede Kullanılan Piezoelektrik Sensörlerin Değişen Sıcaklıklarda Davranışının İncelenmesi
Öz
Yapısal sağlık izleme (SHM),
yapıdaki hasarın yeri ve boyutunu, yapının ömrünü tespit etmek için kullanılan
izleme yöntemidir. Bu çalışmada, serbest bir piezoelektrik sensörün davranışı
değişen çevre koşullarına maruz kalmış yapılar göz önüne alınarak elektromekanik
empedans metodu (EMI) kullanılarak
deneysel olarak test edilmiştir ve ANSYS sonlu elemanlar programı kullanılarak
simülasyon çalışmaları gerçekleştirilmiştir. Deneysel çalışmada; oda
sıcaklığında piezoelektrik sensörün empedans ölçümleri tamamlandıktan
sonra, -10 °C ve -45 °C arasındaki
empedans ölçümleri gerçekleştirilmiştir. Sıcaklık düştükçe frekans ve genlik
artmıştır. Simülasyon çalışmalarında ise, deneysel çalışmada kullanılan
piezoelektrik sensörün ANSYS sonlu elemanlar programı yardımıyla harmonik
analiz sonuçları elde edilmiştir. Deneysel çalışmalardan elde edilen sonuçlarda
olduğu gibi, sıcaklık düştükçe frekans ve genlik artmıştır. Deneysel
çalışmalardan ve simülasyon çalışmalarından elde edilen sonuçların birbirine
yakın olduğu görülmüştür.

Investigation of the Behavior of Piezoelectric Sensors Used in Structural Health Monitoring at Different Temperatures
Öz
Structural health monitoring (SHM); is the tracking
method used to determine the location and size of the damage to the structure
and the life of the structure. In this study, the behavior of a free
piezoelectric sensor was experimentally tested using the electromechanical
impedance method (EMI), taking into account the structures exposed to varying
environmental conditions, and simulation studies were performed using the ANSYS
finite element program. In the experimental study; impedance measurements were
performed between -10 °C and -45 °C after impedance measurements of the
piezoelectric sensor were completed at room temperature. The frequency and
amplitude have increased with decreasing temperature. In the simulation
studies, harmonic analysis results were obtained by using the ANSYS finite element
program of the piezoelectric sensor used in the experimental study. The
frequency and amplitude increased as the temperature decreased, as in the
results obtained from the experimental studies. The results obtained from
experimental and simulation studies were found to be close to each other.
