Dairesel ve prizmatik makine elemanlarında oluşan çatlağın deneysel modal analiz yöntemiyle belirlenmesi
Özet
The machine is used as the elements of circular
prismatic parts and vibration response was measured under
external forces. Cracks formed on a sample of each solid
sample were compared with their response. For this purpose,
experimental modal analysis method was used. Frequencies of
each sample was determined separately. Mode shapes were
obtained with the help of FRF. Crack into the sample was
lower than the resonance frequencies. The first mode was
suffered by a large change in shape. Damping ratio was
calculated Deneysel modal analiz son yıllarda bilgisayar destekli
ölçüm cihazlarının gelişmesiyle daha fazla araştırmalarda
kullanılır hale gelmiştir. Bu yöntemle bir makine elemanının
dinamik özellikleri olarak adlandırılan doğal frekanslar, mod
şekilleri ve sönüm oranları deneysel çalışmalar sonucunda
bulunabilmektedir.
