摘要
本文根据电磁场理论,用统一的方法,建立了电机瞬变过程与轴系的扭振、横振及转动相耦联的强非线性微分方程组。经过线性变换与非线性变换,得到了方程组的解。进行了数字计算,得到了启动过程的横振、扭振、转动及电流等变化规律。理论结果和实验结果吻合得较好。
According to the electromagnetic field theory, a set of differential equations are derived for coupling of the transient process for an electrical machine and transverse and torsional vibrations for the rotor by a unified method. A non-dimensional constant coeHicient state equation is obtained by linear and non-linear transformation. Rules of the change are obtained for transverse and torsional vibration, current, and so on in the starting process. The theoretical results are shown to be in good agreement with the experimental resulis.
