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.

Design of a Test Setup for Measuring Dynamic Stiffness of Vibration Isolators Uz, Canan; Özgen, Gökhan Osman; Ciğeroğlu, Ender (2014-01-01) In this paper, design efforts to develop a custom test setup for measuring dynamic stiffness of vibration isolators are presented. The setup is designed to conduct dynamic stiffness measurements for various static preload values and over a certain (target) frequency range. Direct Method has been selected among the methods defined by standards found in the literature. In order to investigate the effect of basic design parameters of the test setup on its overall performance, an equivalent eight degree of free...
Dynamic stiffness-based test systems for viscoelastic material characterization: Design considerations Özgen, Gökhan Osman; Batihan, Ali Cagri (2012-07-24) In this paper, several important design issues for viscoelastic material characterization test systems which utilize dynamic stiffness measurements are discussed. These discussions are focused on structural dynamics aspects of the design of these test systems. These test systems are used to experimentally obtain the complex modulus of viscoelastic solids such as rubber, plastics, etc. Various standards exist on dynamic stiffness-based viscoelastic material characterization test methods, which give general g...
Design, fabrication, and characterization of micro thermal actuators Gülcüler, Buğrahan; Azgın, Kıvanç; Department of Mechanical Engineering (2020-11) This thesis presents the design, fabrication, and characterization of V-Type thermal actuators, which will be used in an actuator system that is planned to be a tensile and compressive test setup to characterize the expandible cells by the help of double- ended tuning fork resonators as a force sensing mechanism. Actuators are serially packed to increase the generated force by them while maintaining the same deflection values. They have been connected to the overall system by springs to create a force on te...
Design of a tuned vibration absorber for a slender hollow cylindrical structure Aksoy, Tuğrul; Özgen, Gökhan Osman; Acar, Bülent (Informa UK Limited, 2020-09-01) In this paper, details of the design work for a tuned vibration absorber to be used on a hollow cylindrical structure is presented. The vibration problem is of resonant type and the tuned vibration absorber is designed to suppress the displacement vibration response of the free end of the slender hollow structure dominated by the contribution of its lowest transverse vibration modes. The structure is modeled using a commercial finite element software. Finite element model of the structure is verified using ...
Development of a test system for viscoelastic material characterization Erol, Fulya; Özgen, Gökhan Osman; Department of Mechanical Engineering (2014) Viscoelastic materials are used extensively as a means of vibration control and isolation in many vibrating structures. For example, damping instruments utilizing viscoelastic materials such as surface damping treatments and vibration isolators fabricated of viscoelastic materials such as machinery mounts are widely used in automotive and aerospace industries for the purpose of vibration and noise control and isolation, respectively. Viscoelastic materials, as the name implies, behave in between a purely el...
