Titreşim parametrelerinin dönen mekanik sistem dinamiğine etkilerinin araştırılması

Dönen mekanik sistemlerin dinamik davranışının analizini gerçekleştirmek için bir "Düz Bağlantılı Rotor Sistemi" imal edilerek, çeşitli işletme şartları için sistem, titreşim parametreleri yönünden araştırılmıştır. Sistemin dinamik davranışını izlemeye yönelik olarak, planlanan deneylerden, tek diskli mil sistemi (De Laval Rotoru) üzerinde çalışılmış ve mil-yatak sisteminde meydana gelebilecek hata yönünden değerlendirmeler sunulmuştur.

Investigation of effects of vibration parameters on rotating mechanical system dynamics

In order to analyze dynamic behavior of rotating machinery systems a direct coupled rotor system has been designed and manufactured and the system for various working conditions in regard to vibration parameters has been investigated. To observe the dynamic behavior of the system, the planned experiments for De Laval Rotor System have been implemented and the results of fault diagnosis have been presented.
