摘要
大型电机转子由于构造需要而引起弯曲刚度周期性的变化,从而产生失稳和倍频振动. 本文用福洛开理论和多尺度方法,分别研究了其稳定域范围和引起倍频振动的各种因素.
The transversal rigidity of electric motor's rotor during its rotation is periodically varying due to its non-axisymmetric cross section of the shaft. Multiple frequencies vibration and even unstable vibration of the rotor will possibly take place. The reason is analysed by use of Floquet theory and multiple scales method in the paper.
