Determining
of dynamic behaviours of the many machine elements used in the industry is an
important issue in terms of the safe operation of the structure and the
performance of the machine. Modal analysis method is widely used to determine
the dynamic properties of the structures. In this study, theoretical and
experimental modal analyses of a clamped-clamped U frame. Theoretical modal
analysis is performed using ANSYS programme. Experimental modal analysis is
performed with OROS Or36 vibration analyser and OROS modal analysis software.
The results obtained from experimental and theoretical studies were compared
and it was found that the model created in ANSYS successfully represented the
experimental model.

Endüstride kullanılan birçok
makine elemanının dinamik davranışlarının belirlenmesi, yapının güvenli bir
şekilde çalışması ve makinenin performansı açısından oldukça önemli bir
konudur. Modal analiz tekniği yapıların dinamik özelliklerinin belirlenmesi
amacıyla yaygın bir şekilde kullanılmaktadır. Bu çalışmada iki ucu ankastre bir
U çerçeve yapının teorik ve deneysel modal analizleri gerçekleştirilmiştir.
Teorik modal analiz ANSYS programı kullanılarak yapılmıştır. Deneysel modal
analiz ise OROS Or36 titreşim analizörü ve OROS modal analiz yazılımı ile
gerçekleştirilmiştir. Deneysel ve teorik çalışmalardan elde edilen sonuçlar
karşılaştırılmış ve ANSYS’te oluşturulan modelin deneysel modeli başarılı bir
şekilde temsil ettiği görülmüştür.
