The objective of this paper is to obtain stiffness curves of rubber bushings which are used in automotive industry with hyperelastic finite element model. Hyperelastic material models were obtained with different material tests. Stress and strain values and static stiffness curves were determined. It is shown that, static stiffness curves are nonlinear. The level of stiffness affects the vehicle dynamics behaviour.
Bu çalışmada, otomotiv endüstrisinde kullanılan kauçuk burçların hiperelastik modellenmesi yapılmış ve sonlu elemanlar yöntemi ile statik analizleri gerçekleştirilerek rijitlik eğrileri çıkarılmıştır. Kauçuk malzemelerin hiperelastik malzeme modelleri malzeme testleri sonucu belirlenmiştir. Kauçuk burcun belli oranda x,y,z eksenleri yönünde sıkıştırılması ve eksenel yönde burulması sonucu oluşan gerilmeler ve yer değişimleri incelenerek statik rijitlik eğrileri çıkarılmıştır. Rijitlik eğrilerinin doğrusal olmayan karakteristikte olduğu belirlenmiştir. Burç rijitlik değerleri araçlarda sürüş dinamiğini etkileyen önemli parametrelerden birisidir.
