| Abstract: | According to the mechanoelectric analysis dynamics,the magnetic complement energy in air gap of a generator is acquired.The electromagnetic forces on the rotor of the generator are obtained.A mathematical model of coupled bending and torsional vibration of shaft system of the generator excited by electromagnetism is established.It is a continuous mass model.Unbance,gyroscopic,rotary inertia,shear deformation and damping are considered in this model.So it is a comparatively accurate model,and it is useful to deal with the laws of vibration of the generator. |
