Design and construction of a folding mechanism for a radar system

Yurt, Hünkar Kemal
In this thesis, a folding mechanism with 1 degrees of freedom is designed and constructed for a two-antenna radar system. The optimum mechanism for the problem is systematically selected among the conceptual mechanism alternatives. Then, a detailed synthesis and analysis study is performed on the selected mechanism, and the mechanism is implemented to the geometry of the radar system. By performing modal and strength analyses on the 3D model of the folding mechanism created during the implementation study, the design is improved and finalized according to the system requirements.


Improving performance of a remote robotic teleoperation over the internet
Arslan, Mehmet Selçuk; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2005)
In this thesis study, it is aimed to improve the performance of an Internet-based teleoperation system enabling the remote operation of a 6 DOF industrial robot. In order to improve the safety and efficiency of the teleoperation, stability and synchronization (hand-eye coordination) are considered. The selected communication medium between the human operator and remote robot is the Internet. The variable time delays and nondeterministic characteristics of the Internet may lead to instability of the teleoper...
A Functional design methodology with genetic algorithm optimization to a door actuation mechanism
Akman, Hasan; Turgut, Ali Emre; Department of Mechanical Engineering (2019)
In this thesis, the preliminary design of an in-flight refueling door actuation mechanism is designed. A novel design methodology is introduced to create and evaluate different mechanism design alternatives systematically. The design is divided into two sub-problems. For each sub-problem, different conceptual design alternatives and evaluation criteria are created considering the design requirements. Suitable concepts are systematically selected among the alternatives based on the evaluation criteria. Then,...
Design of dual polarized wideband microstrip antennas
Yıldırım, Meltem; Alatan, Lale; Department of Electrical and Electronics Engineering (2010)
In this thesis, a wideband dual polarized microstrip antenna is designed, manufactured and measured. Slot coupled patch antenna structure is considered in order to achieve the wideband characteristic. Although rectangular shaped slot coupled patch antennas are widely used in most of the applications, their utilization in dual polarized antenna structures is not feasible due to space limitations regarding the positioning of two separate coupling slots for each polarization. For a rectangular slot, the parame...

Circular arrays of log-periodic (LP) antennas are designed and their operational properties are investigated in a sophisticated simulation environment that is based on the recent advances in computational electromagnetics. Due to the complicated structures of the trapezoidal-tooth array elements and the overall array configuration, their analytical treatments are prohibitively difficult. Therefore, the simulation results presented in this paper are essential for their analysis and design. We present the des...
Design and Implementation of Transmitting and Receiving Antenna Pair on Flat Ring Surface
Haykir, Yigit; Karadağ, Savaş; Dagdeviren, Birkan; Demir, Şimşek (2018-11-02)
In this work, design and implementation of broadside altimeter antenna on circular ring surface are performed. Utilizing array factor formulation, possible locations for circular array elements are chosen. Slitted microstrip patch antennas are used for an efficient design. Satisfactory results are obtained for an altimeter antenna that can be utilized in missile, aircraft or spacecraft applications.
