NEW TYPE RELIEF VALVE USING MAGNETO-RHEOLOGICAL FLUID

摘要

Magnet-rheological fluid (MR fluid) is a class of smart material whose rh eological properties may be rapidly varied by the application of a magnetic field. Using this rheological property, a new type relief valve is developed in this paper. Traditional hydraulic relief valve has a complex construction and its moving part, for example, the spring often break down during the work. Thus the characteristics and life of relief valve are affected greatly by the moving parts. Using the rheological property of MR fluid, the new type MR fluid relief valve can be designed absence of moving parts. In this paper, the construction and working principle of new type valve are introduced. Its steady-state performance is simulated and experimented.
