STIFFNESS GENERATION APPARATUS, CONTROL METHOD AND HAPTIC FEEDBACK PROVIDING APPARATUS USING THEREOF

摘要

PURPOSE: A stiffness realizing device, a control method thereof and a haptic feedback providing apparatus are provided to reduce power consumption and to recover rapidly by fixing a magnetic application member and moving a relatively light inner moving member up and down. CONSTITUTION: A stiffness realizing device comprises a case(400), a top plate(100), a magnetic field application member(300), an inner moving member(200), and a receiving member(600). The case accepts Magneto-Rheological Fluid. The top plate is arranged on the case and has an impact on external force. The magnetic field application member is arranged in the case and applies the magnetic field to the Magnetic Rheological Fluid. The inner moving member is connected to the top plate in the shape of covering the outer side of the magnetic field application member and moves up and down. The receiving member accepts the magnetic rheological fluid which is flown out by the movement of the inner moving member. Stiffness is realized as the resistance to the external force based on the intensity of the magnetic field. The top plate and the inner moving member are connected by an elastomeric.
