Bu
çalışmada, pasif süspansiyon sistemine sahip bir uçak iniş takımının
titreşimleri MR damperli yarı-aktif süspansiyon sistemi yardımıyla azaltılmaya
çalışılmaktadır. Yarı-aktif bir eleman olan MR damper nonlineer karaktere sahip
olup, oluşturduğu sönüm kuvveti, MR dampere uygulanan gerilim ile
değiştirilebilmektedir. Bu amaçla, MR damperlere gönderilen gerilimin 2
volttaki durumuna göre tasarımı yapılmıştır. Tasarlanan MR damperler yardımıyla
gerilim belirlenerek sönüm kuvveti değiştirilmekte ve titreşimler
azaltılabilmektedir. Benzetim çalışmaları sonucunda, tasarlanan MR damperlere
uygulanan gerilimlerin titreşimlerin azaltılmasında etkin rol oynadığını
göstermiştir.

work, an aircraft landing gear vibrations having passive suspension system, has
been tried to reduce by a MR damper semi-active suspension system. MR damper
being a semi-active component, has a nonlinear character and its damping force
can be changed with the voltage applied to MR damper. For this purpose, the
design of voltage sent to MR damper was done depending on the status of volt 2.
The damping force is changed with the voltage
determined and vibrations can be reduced with the help of MR dampers.
The result of simulation works showed that the voltage applied to the MR damper
has an active role in reducing vibration.
