Abstract
The invention discloses a linear electromagnetic damper with a thread structure. The linear electromagnetic damper comprises a damper touch end, a damper rotation structure, a damper energy consumption structure and a damper base. The damper touch end is connected with the damper rotation structure, and linear motion is changed into rotation motion; the damper rotation structure is connected with the damper base; the damper energy consumption structure is connected with the damper base. The damper touch end is hollow and threads are formed in the damper touch end which is connected with separation teeth I through a ball; when external force acts on the touch end so that the touch end moves downwards, the ball rolls on the internal threads, and the separation teeth I perform rotation motion in the touch end; when the separation teeth drive a rotor to rotate, induced current is generated in a closed circuit through flux change of a coil on a stator salient pole; rotation mechanical energy of the rotor is changed into electric energy in a circuit, and the electric energy is consumed by a resistor R. The stress action of the rotor provides damping force in the magnetic field, and rolling fiction force of the ball in the internal threads also provides partial damping force.
