Abstract

Use of intelligent materials has been a more widespread technology in the last ten years inthe area of research and development of mechatronic equipments. It’s main reason is that someproblems of the utilization needed such a solution, which couldn’t be solved only with new materialsproduced by material texture modification.A claim has come up in the research of the mechatronical systems to develop materials that can getand understand an information from a computer and change their attribution accordingly. Theconnection, what we can establish between the computer and material, sets a limit to the qualitycharacteristics that can be operated by the computer. This transposal can be ensured by effects that’sinduction and abolition rate can be compared or the control is bigger just as the velocity of the changeof a material characteristic. From a control technology viewpoint using electric or magnetic field is themost obvious.One group of these materials is electro-reologic (ER) liquids that change their shear strengthaccording to the electric field. The flow qualities of the ER liquids can be continually changed insidecertain borders, with orders of magnitude shorter interval from the previous hydraulic solutions.Making an opportunity by to create faster controlling and regulating systems from the present ones.The main aim of this work is the modification of basic properties of this kind of liquids and specificationof its utilization possibilities in mechatronic systems such as hydraulic control equipments.Mathematical model as well as its numerical solution of a flow control valve (ER valve) as anappropriate element of hydraulic systems has been prepared during this work. Function tests of thisunit have been carried out by computer aided simulation of the above mentioned mathematical model.
