Ultra magnetostriction execution and its control partapplication in fluid Dietmar Reinert, Emmanuelle BrunHYPERLINK \l /implicit0a and Eva Flasp?lerHYPERLINK \l /implicit0a aBG-Institute for Occupational Safety and Health (BGIA), Alte Heerstra?e 111, D-53757 Sankt Augustin, Germany Abstract：The ultra magnetostriction material is one kind of newfunction material， in the consult massive literature foundatio，introduced the ultra magnetostriction execution principle andclassified and its in the fluid control part applied research presentsituation， and has carried on the forecast to the ultramagnetostriction execution in the fluid machinery applicationprospect. Key word： Ultra magnetostriction Execution Fluid control part Introduction The hydraulic servo performance mainly is decided to composes thissystem the valve, pumps with fluid and so on oil motor controls thepart the performance. Therefore enhances the fluid to control the partthe performance always is peoples diligently goal. The traditionalfluid control part mainly uses the electric motor, the electro-magnetachievement actuates the part. In recent years, along with some newfunction materials appearances, made large scale to enhance the fluidto control the part the performance possibly to become. The ultramagnetostriction material is one kind of new electricity (magnetism) -the mechanical energy transformation material, has under the roomtemperature should the variable lamda big, energy density high, thespeed of response is quick and so on the characteristic, overseas byapplies it to the servo valve, the proportion valve and miniaturepumps and so on in the fluid control part, and has made some progress.This article makes an introduction on this aspect situation. Ultra magnetostriction execution 1.1 ultra magnetostriction materials [ 1 ] [ 2 ] The ultra magnetostriction material (Giant Magnetostrictive Material)does not have to the traditional magnetostriction material (Fe, Co, Niand so on),
