Burada, literatürde yer alan viskoelastik malzemeler için geliştirilmiş matematiksel modellere sistemin kütle değişkeni de ilave edilerek daha gerçekçi modeller oluşturulmuştur. Daha sonra, viskoelastik malzeme modellerinin hidrolik test sistemi ile birleştirilmesiyle birlikte test sisteminin genel modeli elde edilmiştir. Bu kapsamda, katı ve sıvı viskoelastik modeller ayrı ayrı ele alınmış ve analiz edilmiştir. Parametrik simülasyonlarla yapılan dinamik analizlerde, viskoelastik model parametrelerinin malzeme üzerinde oluşan kuvvet, hız ve yer değiştirme gibi dinamik cevaplara etkileri ortaya konmuştur. Bu çalışmadan elde edilen bilgiler ışığında, malzeme karakterizasyon testlerinden elde edilecek veriler kullanılarak testi yapılan malzemelerin dinamik model parametrelerinin kestirimi ve bunlara ait dinamik model kurulumu daha kolay yapılabilecektir. KW - Viskoelastik Malzeme KW - Elastomer KW - Dinamik Karakterizasyon KW - Hidrolik Test Sistemi KW - Servovalf N2 - In this study, hydraulic actuator test system, which is used in static or dynamic characterization tests of machine parts such as bushing with elastomer material, is modeled. Here, more realistic models were created by adding the mass variable of the system to the mathematical models developed for viscoelastic materials in the literature. Then, the general model of the test system was obtained by combining the viscoelastic material models with the hydraulic test system. In this context, solid and liquid viscoelastic models are handled and analyzed separately. In dynamic analysis with parametric simulations, the effects of viscoelastic model parameters on dynamic responses such as force, velocity and displacement on the material have been revealed. In the light of the information obtained from this study, using the data obtained from the material characterization tests, it will be easier to estimate the dynamic model parameters of the tested materials and to set up their dynamic models.
