| description | The invention belongs to the technical field of permanent magnet magnetic transmission, and discloses a hysteresis loop energy conservation permanent magnet coupling magnetic damping calculation method. According to the method, a three-dimensional magnetic equivalent model of the permanent magnet coupling is utilized, external force is applied to an inner rotor to enable the inner rotor to generate forced vibration, torque values of the inner rotor and an outer rotor of the permanent magnet coupling at different moments are calculated respectively, and a hysteretic loop curve of the torque values changing along with angular displacement at different moments is formed; and calculating the area enclosed by the hysteretic loop according to an elliptical area formula, namely the energy dissipated by the permanent magnet coupling in a vibration cycle due to the magnetic damping, inversely calculating the magnetic damping of the permanent magnet coupling according to an energy conservation effect, and accurately ob |
