摘要
依据机电分析动力学理论 ,找到了发电机组定转子间气隙磁场的能量 ,得到了作用在发电机转子上的电磁力 (矩 ) ,建立了一个基于分段连续质量的发电机组轴系弯扭耦合电磁激发振动的数学模型 .该模型考虑了不平衡、陀螺力矩、转动惯量、剪切变形及阻尼的影响 ,是一个比较精确的模型 .
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.
