Two groups of first induction coils 8 are clamped and pressed at the bottom in the cradle shell 2, the first induction coils 8, the hydraulic push rod damper 11 and the balancing instrument 10 are all connected with an external power supply and control equipment through external wires 14, the first induction coils 8 are magnetic field coils and are used for providing a fixed cutting magnetic field for the moving second induction coil 9, under the magnetic field environment, a conductor in a closed loop can generate action counter force when cutting magnetic lines of force move, namely damping force, the damping force changes along with the moving speed of the conductor, according to the lenz law, if the induced current is generated by the conductor forming the loop when cutting the magnetic lines of force move, the ampere force of the magnetic field force borne by the moving conductor always resists or blocks the movement of the conductor. From the perspective of energy conservation, the kinetic energy of the conductor in the magnetic field environment can be converted into potential energy. Based on the principle, the electromagnetic induction damping vibration attenuation device is designed, and the vibration of the cradle is applied to magnetic induction linear cutting, so that the ampere force is generated and the suppression of the cutting vibration of the cradle is realized. According to the electromagnetic principle, the current required to pass can be obtained through PID calculation according to data fed back by the MEMS balance gyroscope, a proper magnetic field is generated, and then the coil passes through magnetic fluxes with different change degrees, so that the cradle swing tends to be smooth.
