Design, control and optimization of vehicle suspensions with inerters
Gerger, Ozan; Ciğeroğlu, Ender; Başlamışlı, Çağlar; Department of Mechanical Engineering (2013)
Inerter is proposed as a mechanical equivalent of the capacitors available in electric circuits. The main advantage of the inerter is to provide a wider design space for a vehicle suspension by adding another suspension element next to spring and damper. Therefore, fine tuning of a suspension performance can be made without subjected to heavy trade-offs. The effect of the addition of inerter to a vehicle suspension and performance of the selected suspension arrangements with passive and semi-active inerters...
Analysis of whiplash during rear crash and development of an anti-whiplash seat mechanism
Özdemir, Mustafa; İder, Sıtkı Kemal; Gökler, Mustafa İlhan; Department of Mechanical Engineering (2013)
Whiplash injury is one of the most important types of injuries when its resulting longterm pain is considered. This neck injury is frequently seen in the motor vehicle collisions, especially in the low-speed rear collisions. In this thesis, it is aimed to analyze the whiplash syndrome in low-speed rear-end impacts and develop an antiwhiplash seat mechanism that reduces the risk of occurrence of whiplash injuries. Firstly, using the commercially available finite element model of the BioRID II dummy, backset ...
Thermodynamic and structural design and analysis of a novel turbo rotary engine
Ercan, Taylan; Akmandor, İbrahim Sinan; Department of Aerospace Engineering (2005)
A novel turbo rotary engine, operating according to a novel thermodynamic cycle, having an efficient compression phase, a limited temperature combustion phase followed by a long power extraction phase is designed. Thermodynamic and structural design and analysis of this novel engine is carried out and two prototypes are manufactured according to these analysis. High performance figures such as torque, power and low specific fuel consumption are calculated. Also the component tests of the manufactured protot...
Frequency domain computation of turbofan exhaust noise radiation
Ulusoy, Yavuz Barbaros; Özyörük, Yusuf; Department of Aerospace Engineering (2006)
In this study, acoustic noise radiation through a duct in frequency domain is analyzed. Frequency domain linearized Euler equations are solved for turbofan exhaust noise propagation and radiation. The geometry in studied cases is assumed as axisymmetric. The acoustic waves are decomposed into periodic azimuthal modes. Characteristic boundary conditions, and buffer zone boundary conditions are employed. Iterative type pseudo time integration is employed. Nonuniform background flow effect on the radiation pat...
Self-regulatory driving practices of old and young drivers
Azık, Derya; Özkan, Türker; Department of Psychology (2015)
The aim of the current study was to investigate self-regulatory driving practices of old and young drivers by examining underlying factors and possible benefits on drivers’ aberrant behaviors. 258 active male drivers (120 older, 138 younger) participated in the study. Older drivers’ age range was determined as 60-75 and younger drivers’ age range was determined as 21-30. For testing motivator factors of self-regulatory driving practices, Health and Functional Abilities Scale (Molnar et al., 2013), Self-Rate...
