In this papers, a new type of Magnetorheological Fluids continuously variable transmission (MRFCVT) with V-shape working gap and Self-pressurized structure was given, introduced the work principle and structure, also deduced the dynamical equation and Self- pressurized formula of MRFCVT, did some simulative caculation about virtual prototype in two-dimension static magnetic field using finit element method, an explicit conclusion was drawn that this new type of MRFCVT which was reinforced by the self-pressurized structure can be applied in power transmission domain.MRF, Self-pressurized, Simulation, CVT
