Experimental Modelling of Resistance Spot Welding of Advanced High Strength Steels
(Fen Bilimleri Enstitüsü, 2023)
The use of advanced high strength steels (AHSS) is becoming more dominant in the automotive industry due to the excellent balance of strength and lightness of these steels. Although the use of AHSS metals is increasing, ...
Robust Autolanding System Design for a Combat Aircraft on the Ground
(Fen Bilimleri Enstitüsü, 2023-02-01)
Within the scope of this thesis, a 6-degree-of-freedom model of a combat aircraft is
created. Apart from the flight dynamics, landing gear dynamics on the ground are also
modeled. After that, a robust autolanding system ...
Hydrodynamic Optimization of the Submarine with a Fully Parametric CAD Model
(Fen Bilimleri Enstitüsü, 2023-02)
This study was conducted to compare the performance of four different optimization
studies that can be done to reduce the drag force that a submarine is exposed to in fully
submerged conditions. The submarine used in the ...
Broadband and High Frequency Piezoelectric Energy Harvesting System With Curved Panels For Passive Vibration Isolator
(Fen Bilimleri Enstitüsü, 2023-02-01)
In military aircrafts, random vibration occurs with high amplitude in broad frequency
spectrum. High vibration profiles, which affecting electronic units, can cause fatigue over
time and damage mechanics and electronic ...
Modelling and Analysis of Legged Robots with Temporary Flight Capabilities
(Fen Bilimleri Enstitüsü, 2022)
The high obstacle-crossing potential of legged robots has made them a widely studied subject. However, the obstacles that can be overcome are generally proportional to the length of the legs. And any study, that states a ...
Intelligent Control of Refrigerators and Freezers
(Fen Bilimleri Enstitüsü, 2022-12)
As the number of consumers has been growing and global warming continues to affect the environment, the refrigeration sector is becoming an increasingly important part of the global economy. Refrigeration products have ...
Thermal Behavıor of Lıthıum-Ion Batterıes Under Normal and Abuse Operatıng Condıtıons
(Fen Bilimleri Enstitüsü, 2022)
This doctoral thesis investigates the electrical and thermal behaviors of Li-ion battery cells during the normal and abnormal conditions using the experimental and modeling methods. First, various standard battery tests ...
Kinematic Design and Analysis of Munition Ejector Release Unit
(Fen Bilimleri Enstitüsü, 2023)
In this study; design, analysis and optimizations will be done to open the hanger handles at fixed intervals on the ammunition attached to a release mechanism. The hook arms are held by the mechanism and release the hook ...
Multibody Simulation of Coupled Aerodynamics and Structural Model of a Helicopter Main Rotor
(Fen Bilimleri Enstitüsü, 2023-02-02)
The use of helicopters has been on the rise since their invention, particularly due to their ability to perform axial and hover flights. However, designing a helicopter rotor is a complex process, as it involves understanding ...
Dynamic Characterisation of Human Neck For Impact Applications
(Fen Bilimleri Enstitüsü, 2023)
The neck is the part of the spine and has highest risk of injury in traffic accidents. Neck trauma can occur in several types of collisions, but rear-end collisions have the highest risk of trauma. Human neck models are ...
