摘要
应用ANSYS分别对某超导发电机内转子、外转子和转子整体进行模态分析.考虑内转子中挠性支撑结构,将外转子轴承约束简化为弹性约束.考虑该弹性约束刚度的影响,获得内、外转子的前10阶固有频率和振型图;针对双层转子结构整体,对比分析结构中内、外转子的振动形式,获得转子的固有振动特性.
The modality of the inner rotor, the outer rotor and the whole rotor are analyzed for a superconducting generator by ANSYS. Considering the flexible supporting structure in the inner rotor, the constraint of the beating of outer rotor is simplified as elastic constraint. Considering the effect of the elastic constraint stiffness, the first ten natural frequencies and the vibration shape figures of the inner rotor and the outer rotor are obtained. For the whole double-decks rotor structure, the vibration shapes of the inner rotor and the outer rotor in the structure are compared, and the natural vibration characteristics of the rotor are obtained.
