Acoustic fatigue procedure validation and application on cavity wall Küden, Zeynep; Çalışkan, Mehmet; Department of Mechanical Engineering (2019) Acoustic loading formed due to boundary layer fluctuation, engine efflux and separated aerodynamic flow cause vibration that may result in fatigue failure of the structure. The subject of this thesis deals with the analytical acoustic fatigue procedure composition and validation in addition to critical wall stress analysis of representative weapon bay. It is aimed to feed the design process of the projects during its preliminary stages from structural point of view. The thesis can be discussed into two sect...
Multi shooter localization with acoustic sensors Akman, Çağlar; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2017) This thesis proposes a generalized estimation framework for acoustic based shooter localization system relying on time of arrival (ToA) and direction of arrival (DoA) of gunshot acoustic events, namely muzzle blast and shockwave. This framework is valid in case both acoustic events are present or one of them is missing. Furthermore, it provides a solution not only for a single shooter but also for simultaneous multiple shooters. As regards to details, this thesis proposes a DoA estimation method based on be...
Noise path identification for vibro-acoustically coupled structures Şerafettinoğlu, A. Hakan; Çalışkan, Mehmet; Department of Mechanical Engineering (2004) Structures of machinery with practical importance, such as home appliances or transportation vehicles, can be considered as acoustically coupled spaces surrounded by elastic enclosures. When the structures of machinery are excited mechanically by means of prime movers incorporated into these structures through some elastic connections, generation of noise becomes an inevitable by-product. For noise control engineering purposes, a thorough understanding of emission, transmission and radiation of sound from s...
Acoustic wave analysis using different wave propagation models Yıldırım, Baran; Akgöz, Yakup Cevdet; Department of Engineering Sciences (2008) In this study in order to simulate the acoustic waves, Ray Theory and Normal Mode models are used. These methods are analyzed using MATLAB simulation tool; differences between two models are examined and a region with a known bottom profile and sound velocity profiles is investigated. The Ray Theory is used in acoustic systems which is the one of the applications of wave modeling. Ray theory is solved with standard Ordinary Differential Equation solvers and normal mode with finite element method. Different ...
Developing a tool for acoustical performance evaluation throughout the design Özgenel, Çağlar Fırat; Sorguç, Arzu; Department of Architecture (2012) Performance of the buildings has always been a concern for the architects. With the enhancements in the technology, it is possible to measure, analyze and evaluate the performance of an architectural design before it is built via simulation tools developed. With the evaluation of the analysis performance of the concerned space can be upgraded if simulation tools are employed throughout the design process. However, even though the simulation tools are developed for the acoustical simulation and performance a...
