摘要
在工程中 ,两极电机转子等具有矩形截面的轴 ,由于不同方向上的弯曲刚度不同而引起振动 ,即使激振频率远离系统自然频率 ,也可能产生较大响应而造成破坏 ,这就是参数激励共振。所以 ,研究参数激励系统的稳定性及其稳定区域 (范围 )是很重要的。本文以非对称刚度转子和实际电机转子截面轴转动时的弯曲振动为例 。
In the application of engineer, the shaft or motor rotor which has the rectangular section vibrates hard to be broken for it's non symmetry rigidity, even the excited frequency deviates far from the natural frequency. This is called parameter vibration. So the research of the stability of parameter excited system and its range of stability is very important and necessary. This theme discusses the range of stability for the different section of motor rotor's bend vibration by means of the theory of Floquet.
