Abstract : People are exposed to sounds in the majority of their lives. Sound can disturb people as well as can comfort. One of the sources causing noise in the environment is the ones caused by aircrafts. Noise of aircraft caused by the engine and the wings occur. Some projects have been done to prevent this noise. In this project, the aim is to reduce the sound pressure level of the wing by the wave modification to be made to the edge of the wing profile. The modification parameters affecting the sound pressure level are wavelength and amplitude. By performing numerical studies, parameter values were found which could have the most positive effect on the sound pressure level. These parameter values are 20, 40 and 50 mm for wavelength, 6 and 8 mm for amplitude. Wing profiles produced according to these parameter values were examined experimentally. In line with the numerical and experimental results, it is aimed to select the model that gives the positive results for aeroacoustic and aerodynamics.

Abstract : The aim of the project is to design an active auto tensioner for Tier-4 engine in tractor. This active controlled tensioner design is developed to apply a constant force to belt to prevent looseness. The purpose of this project is to improve an active controlled tensioner for diesel engine motors with the sponsorship of Türk Traktör. In current system, a manual tensioner has been used to adjust belt tension. Novel active controlled tensioner will be an innovative design that can apply appropriate tension to belt. So, problem definition was done for understanding main problem. Design specifications was specified for meeting to customer requirements. To find similar work about automatic tensioner, many auto tensioner products and other related works were researched and so, state-of-the-art review was done. As the result of researches, conceptual design was determined. After doing necessary calculations and analyzes, a virtual model was developed by taking into consideration design specifications. In virtual model section, it was shown that active controlled tensioner model was created as a solid model. In test section, necessary tests which was done to validate system were executed. In Conclusion and Discussion section, possible improvements on the system was discussed.

Abstract : Electric locomotive is commonly preferred in tunnel construction. Since there is no fuel consumption and therefore has no risk concerning the human health and environmental factors. The aim of the project is to develop and design electric locomotive with RFID module to provide the communication since it is an issue concerning the working environment of the vehicle. Mechanical and electrical design of the locomotive is done regarding to this very project and strength analysis of the design is performed. Before prototyping, to reduce costs of buying physical items, a simulation model is designed. In this simulation model, our aim is to observe system response and observe if our results meet with our design specifications. Implementation processes and testing of the prototype is formed. A scaled model of the designed locomotive is built with the same specifications as the prototype locomotive.issues, it is decided to produce a model instead a prototype. Electronic and mechanic system is combined in this project.

Antibody Printer

Proje Öğrencileri: S. ŞENİPEK, İ.M. KILIÇ, D.B. DALGIÇ, O. RIDVANOĞLU

Proje Danışmanı : Dr. Ender YILDIRIM

Abstract : Within the scope of the project, an antibody printer has been designed, performed and tested for antibody laying in the desired region in microfluidic structures containing antibody-based biosensors.The antibody consists of a printhead which allows the printer to be placed on a micro-fluidic bed (thermoplastic or paper-based) to be printed, and to transfer the antibody onto the microfluidic substrate via a printing table which can be moved in two axes on the horizontal plane.The antibody transfers the antibody patterns of at least 45 µm wide antibody patterns between the two axes along the two axes in the horizontal plane to the microplate slide on the standard microscope slide. The printhead transmits the antibody to the substrate with a flow rate of at least 100 µl / min. For the above mentioned purposes, the components were produced and tested separately.

Abstract : This project is carried out with Hidromek AS. The problem was reported by Hidromek. According to this, Hidromek wants to produce the axles imported from abroad in its new factory. It is one of the aims to reduce imports and employ the people of the country. The axial force that comes into the axle must come out of the same axis. This force must be 6 times greater than the given force. A gear mechanism that provides the desired features in the axle is the problem of the Project. The axles used previously and the axles used by the other brands in the market are examined in depth and we are given specific gear numbers and the desired torque value. The planetary gear system in the axle, according to the number of gear given to us to choose the most appropriate design and after making the necessary calculations. Our main goal is to provide the required torque value. Because the size of the axis is certain we need to pay attention to the dimensioning. This is one of the design constraints. The other is the required movement due to the shaft and the bearing can combine with certain gears. Their dimensions should be enough to fit inside the axle.

Abstract : In this experiment, fluid mechanics formulations learned in previous years is used. Moreover, the purpose of this experiment is to make the best way to put new information in literature. Another purpose of this experimental setup is to make use of laboratory experiments in fluid mechanics courses by students. A literature review is conducted, material selections to be used on the table are decided and cost analysis is performed. Also, a patent investigation of the experimental setup is carried out. Research has shown that the velocity of water can change the flow characteristics of the water. So, the flow of water can be made laminar, transitional and turbulent. The purpose of this experiment is to show the characteristic of the flow and study flow kinematics for different orientations of obstacles.

Abstract : The project is sponsored by Optima. After conducting research on the company, a start-up meeting was held with the company to discuss our project. A timeline for our group was determined at this meeting. It was determined how to work and what to do on a weekly basis. This timeline is of great importance for the operation of the project. Then, features and design requirements for automatic garage door design were determined. As a result of meetings with our sponsor and supervisor, the appropriate design was indicated. For the motor to be used in the project, the motor selection was made from a company determined by the sponsor. Automatic garage door panel, motor, reducer, sliding and driving mechanism was decided. Depending on motor power and output torque, the mathematical calculations of the gear unit have been made. In order to create shaft and sliding mechanism, necessary mathematical calculations were made. Designs based on these calculations were continued under the control of our industrial and academic supervisor. During the production phase, the sponsor company was sent to the list of materials to be used in the project. The price list was determined. After the procure of material, production was started in machining. We worked with different collaborative companies to manufacture some parts. After the part production was completed, the assembly process was carried out. The system was tested after assembly.
