(Sinop University, 2025) Şen, Murat; Yıldız, Yunus Onur; Yiğid, Osman; Kara, Sertaç Emre
This study investigates the dynamic characteristics of Nomex composite sandwich structures, which are widely utilized in extensive engineering fields such as aerospace, marine, and automotive industries due to their numerous advantages, including high strength, vibration and sound insulation, and thermal resistance. Considering that these structures typically operate under dynamic conditions, understanding their dynamic properties, such as resonance frequencies, vibration modes, and damping ratios, is crucial for their efficient and safe operation. In the presented study, the resonance frequencies, vibration modes, and damping ratios of Nomex composite sandwich plates were determined using the Experimental Modal Analysis (EMA) method. It was observed that the structure exhibited a significant vibration damping ratio at the vibration modes corresponding to its resonance frequencies.
