In this study a fiber optic interferometer (FOI) was designed and constructed to measure micron level clearances occurring in piston cylinder arrangements. A Cartesian model of the piston cylinder assembly is manufactured and lateral motion and vertical displacement are generated via a step motor, and micrometers, respectively. Clearance measurements are conducted in air and also in a lubricant. The range of vertical displacements is kept between 0-50 μm, and the lateral motion is 13.5 mm. The effect of the step motor and lateral motion carriage on distance measurement is determined and this is used to correct displacement measurements.

Design and analysis of filament wound composite tubes Balya, Bora; Parnas, Kemal Levend; Department of Mechanical Engineering (2004) This thesis is for the investigation of the design and analysis processes of filament wound composite tubes under combined loading. The problem is studied by using a computational tool based on the Finite Element Method (FEM). Filament wound tubes are modeled as multi layered orthotropic tubes. Several analyses are performed on layered orthotropic tubes by using FEM. Results of the FEM are examined in order to investigate characteristics of filament wound tubes under different combined loading conditions. W...
Design and development of fiber optic MEMS microphone measurement system Karaca, Ekin Muharrem; Bayram, Barış; Department of Electrical and Electronics Engineering (2019) In this thesis, fiber optic MEMS microphone measurement system is designed and demonstrated. The displacement of the sensing element of the fiber optic microphone, the membrane, together with the optical components are 3-D modeled and simulated by means of finite element methods. The parameters of the optical system under different measurement conditions are optimized according to the simulation results. Based on the simulation results, the measurement system setup is designed, constructed and functionalize...
Design and implementation of a current source converter based statcom for reactive power compensation Bilgin, Hazım Faruk; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007) This research work is devoted to the analysis, design and development of the first medium power Current-Source Converter (CSC) based distribution-type Static Synchronous Compensator (D-STATCOM) with simplest converter topology and coupling transformer connection. The developed CSC-D-STATCOM includes a +/-750kVAr full-bridge CSC employing Selective Harmonic Elimination Method (SHEM), a 250kVAr low-pass input filter at 1kV voltage level, and a Δ/Y connected coupling transformer for connection to medium-voltag...
Development of a shell finite element for large deformation analysis of laminated composites Yıldız, Tuba; Darendeliler, Haluk; Department of Mechanical Engineering (2008) The objective of the present work is to investigate the behavior of laminated fiber -reinforced polymer matrix composite shell structures under bending load with the help of a modified finite element computer code which was previously developed for the analysis of pseudo-layered single material shells. The laminates are assumed to be orthotropic and the formulation is adapted to first order shear deformation theory. The aim is to determine the large deformation characteristics numerically, and to predict th...
Design and analysis of ultrashort femtosecond laser amplifiers Doğan, Ersin; Bilikmen, Kadri Sinan; Department of Physics (2006) This thesis presents a compact femtosecond laser amplifier design for optical preamplifiers and power amplifiers consist of theoretical perspective, simulations to analyze and optimize beam performance. The propagation through optical media is simulated for every optical component such as mirrors and nonlinear crystal separately and suggested realignment of these components required increasing amplifier performance. Finally Gaussian beam propagation and aberration compensation has been conducted.
