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 freedom lumped parameter model of the test setup is used which takes into account the basic dimensions and materials used for main structural components of the proposed setup design as well as the inertial characteristics of the isolators. Using the equivalent model, virtual tests are performed and the accuracy of the test setup is studied for various testing scenarios. A major work that is conducted as part of this work is to come up with a procedure that will enable tuning of the setup parameters such that the percent error on measured dynamic stiffness of various types of isolators are minimized for the case when various levels of error are present in measured displacement and force amplitudes

Design of a complex modulus test system for viscoelastic materials. Erdoğan, Bilgeha; Özgen, Gökhan O..; Department of Mechanical Engineering (2019) 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 of a test setup for the characterization of vibration isolators Uz, Canan; Özgen, Gökhan Osman; Ciğeroğlu, Ender; Department of Mechanical Engineering (2013) Design of a test setup to investigate dynamic characteristics of a vibration isolator has been extensively studied over the years and international standards are regulated to explain the basis of the measurements. In this thesis, design efforts to develop a custom test setup for measuring dynamic stiffness of vibration isolators are presented.

Design and performance analysis of a pump-turbine system using computational fluid dynamics Yıldız, Mehmet; Albayrak, Kahraman; Çelebioğlu, Kutay; Department of Mechanical Engineering (2011) In this thesis, a parametric methodology is investigated to design a Pump-Turbine system using Computational Fluid Dynamics ( CFD ). The parts of Pump-Turbine are created parametrically according to the experience curves and theoretical design methods. Then, these parts are modified to obtain 500 kW turbine working as a pump with 28.15 meters head. The final design of Pump-Turbine parts are obtained by adjusting parameters according to the results of the CFD simulations. The designed parts of the Pump-Turbi...
Design and development of a complex shear modulus measurement setup for viscoelastic materials Özgen, Gökhan Osman (2005-01-01) Details of the design and development study of a complex shear modulus measurement setup for viscoelastic materials have been presented in this paper. The new setup is specifically designed for measuring the complex shear modulus of pressure sensitive adhesives. The setup consists of a rigid block that is connected to a rigid fixture through two identical shear specimens of the viscoelastic material to be tested. The rigid block and the shear specimens resemble a single degree of freedom system. Once the fr...
Development of an automatic design and analysis tool for axial compressors Kündeş, Necmettin Anıl; Aksel, Mehmet Haluk; Baran, Özgür Uğraş; Department of Mechanical Engineering (2017) In this thesis, an automatic design and analysis tool is developed for the design of an axial flow compressor and to check the required design conditions of the designed compressor by using three dimensional CFD analyses automatically. The developed tool mainly consists of six parts which are mean line design, calculations based on radial equilibrium theory, parametrization, generation of three dimensional blade geometry, mesh generation and solver. A new design study for an axial flow compressor begins wit...
