heal.abstract	The purpose of this thesis is to design and simulate a hydraulic circuit for hydrostatic transmission for use in a commercial vehicle. Firstly, the aim is to develop a model replicating the dynamics of the whole vehicle for which the hydraulic circuit will be used, according to its given parameters. During the simulation, the vehicle will be subjected to various procedures and manoeuvers respective of those which would be faced under natural conditions in order for the dynamic and kinematic characteristics to be estimated to a sufficiently accurate degree. Thus, through this process the necessary data may be collected which are vital for the design and sizing of the hydraulic circuit and its individual components. Following this, the whole hydraulic system will be designed with an open differential using proprietary components including a pump, hydraulic motors, valves and various hydraulic components. For the assessment of the total dynamic response of the hydraulic circuit, a Matlab/Simulink model was developed. Several simulation runs were realized, including the step response, the wheel torque and speed response on various manoeuvers of the vehicle, as well as the response of the system which used a flow divider valve as the implementation of a limited slip differential. Finally, a test rig was designed and manufactured at the Machine Design Laboratory of the NTUA and a series of qualitative tests were carried out from which the concept of the working principle of the open differential was confirmed.	el
