Bu projede özgün salınımlı rotor ve yalpalayan çubuk tipi prototip yönelim kontrol eyleyicileri gelistirilmistir. Öncelikle eyleyicilerin uydu yönelimine etkileri matematiksel olarak modellenmistir. Daha sonra olusturulan matematik modelden çıkarımlar yapılarak tasarım yaklasımları belirlenmis ve eyleyici tasarımları yapılmıstır. Yük hücresi ve dijital-analog dönüstürücü kartlarından olusan deneysel bir düzenekten faydalanarak eyleyicilerin çalısması kaynaklı kuvvet ve moment degerleri ölçülmüstür. Ayrıca tek eksenli bir hava yatagı kullanılarak da deneyler gerçeklestirilmistir ve eyleyicilerin uydu yönelimindeki basarısı gösterilmistir. Yine özgün yalpalayan çubuk temelli mikro elektromekanik seviyesi eyleyici tasarımı da yapılmıstır.

Fatigue life estimation of tuned vibration absorbers with response estimation method Yılmaz, Yunus; Özgen, Gökhan Osman; Department of Mechanical Engineering (2022-5-24) Tuned Vibration Absorbers are designed and used in applications where any unwanted vibration is needed to be elimination from a vibrating system. In order to accomplish that goal TVAs are needed to be designed to absorb vibrational energy on its own at a specified frequency. Since the energy is absorbed from main system to the TVA, this energy will cause high vibration levels on the TVA. Due to the excessive vibration that occurs on the TVA, vibrational fatigue life is a concern for TVA design. Vibrational ...
Simulation of glow discharge plasmas by using parallel particle in cell / monte carlo collision method : the effects of number of super particles used in the simulations Erden, Emrah; Çetinkaya, Tahsin Ali; Rafatov, İsmail; Department of Mechanical Engineering (2013) Mechanical amplification is achieved using a multi-flexure-hinge based compliant mechanism, due to limited displacement range of piezoactuator. In the design stage of mechanism, a comparison matrix analysis is performed to decide the best alternative among the possible compliant mechanism candidates. The mechanical design parameters of the displacement amplifier is determined optimally using the analytical equation derived using Pseudo Rigid Body Model, and the static analysis is performed using finite elem...
A new jacobian matrix calculation method to decrease computational time in periodic force response analysis of nonlinear structures Kızılay, Hazım Sef; Ciğeroğlu, Ender; Department of Mechanical Engineering (2019) The contact interfaces between the components used in high speed systems such as the turbo machinery cause nonlinear vibrations. In order to understand the dynamic characteristic of nonlinear systems, it is important to perform nonlinear vibration analysis. In nonlinear vibration analysis, due to the properties of nonlinear elements used, it is not possible to calculate the Jacobian matrix analytically or it becomes very complicated and difficult, therefore, Jacobian matrix is calculated as numerically. In ...
Comparative design of millimeter wave RF-MEMS phase shifters Kobal, Enis; Demir, Şimşek; Department of Electrical and Electronics Engineering (2016) Phase shifters are widely used for electronic beam steering for various antenna applications. This thesis presents design and comparison of 3 di erent 3-bit transmission type phase shifters, which are switch-line, Distributed MEMS Transmission Line (DMTL) and triple stub phase shifters, realized with capacitive contact Radio Frequency (RF) Micro-Electro-Mechanical Systems (MEMS) switches for Ka-Band applications. For the design of switch-line phase shifter reducing the sensitivity of the electrical performa...
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. 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 ...
