Stiffness generation appatus using magneto-rheological fluid, control method and haptic providing apparatus using thereof

摘要

The present invention relates to a rigid realization device using a magnetorheological fluid, a control method and a haptic providing device using the same. The present invention relates to a stiffness implementing device and a control method and a haptic providing device using the same. To this end, the housing including a magnetorheological fluid; An upper plate provided at an upper portion of the housing and configured to act on an external force; Magnetic field applying means connected to the upper plate and moving in the housing and applying a magnetic field to the magnetorheological fluid; An inner case provided inside the housing and into which the magnetic field applying means can enter and exit; And a receiving means for receiving the magnetorheological fluid flowing out of the inner case by the movement of the magnetic field applying means. The magnetorheological fluid may include a magnetorheological fluid having rigidity with resistance to external force based on the strength of the magnetic field. It provides a rigid implementation and control method using the haptic providing apparatus using the same.;Magnetorheological Fluid, Stiffness, Shear Force, Compression Resistance, Flow Resistance, Coil, Haptic, Damper
