This paper presents the development of models for the hydraulic and mechanical parts of the power steering system of an agricultural tractor. The hydraulic model is built using the component blocks from the Fluids toolbox of the Matlab/Simulink platform. The hydraulic part of the model is then integrated with the mechanical model of the front axle developed using the SimMechanics toolbox. The modeling procedure of the hydraulic system, containing a steering control unit, is described. The overall model allows the examination of the operation of the system, evaluation of system requirements, energy losses, and the necessary modifications to achieve the design goals through simulations.

 Modeling and experimental evaluation of variable speed pump and valve controlled hydraulic servo drives Çalışkan, Hakan; Balkan, Raif Tuna; Department of Mechanical Engineering (2009) In this thesis study, a valveless hydraulic servo system controlled by two pumps is investigated and its performance characteristics are compared with a conventional valve controlled system both experimentally and analytically. The two control techniques are applied on the position control of a single rod linear actuator. In the valve controlled system, the flow rate through the actuator is regulated with a servovalve; whereas in the pump controlled system, two variable speed pumps driven by servomotors reg...
 Modelling and experimental evaluation of an electrohydraulic pitch trim servo actuator Özturan, Ahmet; Balkan, Raif Tuna; Department of Mechanical Engineering (2012) The pitch trim actuator is a hydraulic powered electro-mechanical flight control device of UH-60 helicopters which converts a mechanical input and an electrical command into a mechanical output with trim detent capabilities. In this thesis study, pitch trim actuator is investigated and a mathematical model is developed. From these mathematical equations, the actuator is modeled in MATLAB Simulink environment. While constructing the mathematical model, pressure losses in hydraulic transmission lines and comp...
 Design, construction and control of an electrohydraulic load simulator for testing hydraulic drives Akova, Hayrettin Ulaş; Platin, Bülent Emre; Balkan, Raif Tuna; Department of Mechanical Engineering (2014) In this thesis, an electro-hydraulic load simulator is designed, constructed, and controlled in order to carry out the stability and performance tests of newly developed hydraulic drive and control systems. It is an experimental loading system capable of applying the desired test loads onto the actuator of the hydraulic drive system under test in a laboratory environment. The primary aim of this study is to support the research activities related to the development of hydraulic drive and control systems so ...
 Acquisition of field data for agricultural tractor Koyuncu, Atayıl; Adalı, Orhan; Department of Mechanical Engineering (2006) During the operations of an agricultural tractor, front axle and front axle support encounter the worst load conditions of the whole tractor. If the design of these components is not verified by systematic engineering approach, the customers could face with sudden failures. Erkunt Agricultural Machinery Company, which is located in Ankara, has newly designed and manufactured the front axle support of its agricultural tractors. In this study, the design of 2WD (Wheel Drive) Erkunt Bereket Agricultural Tracto...
 Experimental Investigation of the Anti Vortex Devices of Beyhan 1 Dam and Hydroelectric Power Plant Water Intake Structure Göğüş, Mustafa; Altan Sakarya, Ayşe Burcu; Köken, Mete (2016-06-17) Hydraulic model tests of the intake structure of Beyhan 1 Dam having four units were carried out at Hydromechanics Laboratory of Middle East Technical University, Ankara In order to investigate the flow pattern, and formation, development and dissipation of vortices at the intake structure under different operation conditions of the units, and to determine the types of anti-vortex devices to avoid the air-entraining vortices, a model of 1/29.43 length scale was constructed. The model area covers an about 20...
