Abstract

AbstractThe purpose of this study is to visualize the characteristics of ER fluids as preceding step of developing 3 port ER valves.As the strength of the electric field increases, more clusters in flow are made and these clusters are thought to be thereasons of the load flow rate being increased and the outlet flow rate being decreased. The ER Valves and load and outletflow rate check method are considered to be applied to the fluid power control system. Using the manufactured pressurecontrol valve, a one-link manipulator with FHA in robot system is driven. As a result, it is experimentally confirmed thatthe pressure control valve using ER fluids is applicable to use in driving actuator. If it applies characteristics of the ERfluids, it will be able to apply in the control system for the ER Valve which occurs from industrial controller(PLC).
