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 ...
Impeller Burst Analysis and Validation
(Fen Bilimleri Enstitüsü, 2022-12-15)
The rotating parts in gas turbines are expected to operate safely under different loads, such as
high centrifugation, temperature, and pressure. Due to the high centrifugal forces generated
at high rotational speeds, ...
Immersed Boundary Method for Rotorcraft Aerodynamics Using OpenFOAM
(Fen Bilimleri Enstitüsü, 2022)
The rotorcraft CFD literature review showed that efficient, easy to apply, and computationally
less expensive methods are still a need for the design and performance predictions of
rotorcraft. Immersed Boundary Method ...
Design, Fabrication and Control of A Novel Shape Memory Alloy (SMA)-Wire-Based Flexible Composite Actuator
(Fen Bilimleri Enstitüsü, 2023)
Soft actuators are frequently seen in many design areas. They can adapt to the desired motion and do not harm the material they touch. These features give many ideas to designers. In this thesis, such a soft composite ...
A Tuned Mass Damper Design Based on Eddy Current Damping
(Fen Bilimleri Enstitüsü, 2023)
All dynamic structures encounter vibration during their operation. A structure
experiences the vibration load in an amplified manner at structure’s natural frequencies.
If the amplitude of vibration load is high enough, ...
