In this thesis, the design of test devices for dynamic characterization of elastomer materials and elastomer vibration control components are designed. For this purpose, two different studies are conducted. In the first study, an already installed test setup is modified to provide preloading capability. In the second study, a completely new test setup is established. Conceptual design studies are carried out based on the information obtained in the literature and related standards, then the validity of the design has been investigated with finite element eigenvalue extraction analysis. The consistency of the results is evaluated by frequency dependent comparative tests. Error analysis study is carried out accordingly because the results were not consistent as expected. The effects that could cause these distortions are discussed and comments are made about possible changes. The outputs are aimed to guide the people who will work on this subject.
