Abstract
Bu
çalışmada düz metal yüzlü ve rijit köpük çekirdekli sandviç kirişlerin temel
titreşim frekanslarının ölçümünde konsol kiriş numune boyunun neticelere etkisi
incelenmiştir. Bu maksatla basit bir titreşim deney düzeneği oluşturulmuş ve
imal edilen sandviç kiriş numuneleri üzerinde 3 farklı konsol uzunluğu için
titreşim deneyleri yapılmıştır. Elde edilen deneysel neticeler bir sonlu
elemanlar modeli ile elde edilmiş olan neticeler ile mukayese edilmiştir.
Yapılan mukayese konsol kiriş titreşim deneyi ile sandviç kiriş temel titreşim
frekansının hassas olarak ölçülebileceğini ve numune boyunun artırılmasının
genel olarak hassasiyeti artırdığını göstermiştir.
