NOVELTY - The utility model claims a double-stage friction electromagnetic damper, comprising a soft steel damper, a generating part and a connecting rod for connecting the two; the soft steel damper comprises a core steel plate of dog bone shape, a restraint plate A and a restraint plate B set on the left and right sides of the core steel plate, a restraint unit surrounding the upper and lower surfaces of the core steel plate and a friction plate set on the front and back surfaces of the core steel plate; the grooves of the core steel plate and the restricting unit are paraffin; the generating part comprises an outer cylinder, a generating coil and multiple permanent magnets set in the generating coil; when the soft steel damper is slightly vibrating, the generating part generates current to increase, the material graphene electrified and heated, the paraffin is melted after the paraffin melting point is reached, it has the function of lubricating liquid, the soft steel damper rotates from the original friction energy consumption to enter the second stage of bending energy consumption.
