摘　　要：针对两极汽轮发电机转子下线槽铣削加工完毕后发生特有的转子跳动现象,采用Ansys软件进行了有限元仿真再现,并基于材料力学斜弯曲理论对该现象进行了理论定性分析与验证。研究表明,两极汽轮发电机转子的形心主惯性矩差异,是跳动现象产生的原因之一。Against the unique rotor runout after completion of the milling onto the rotor coil winding slot of two-pole turbine generator, Anays software is applied to reappear finite element simulation, theoretical qualitative analysis and verification is carried out based upon the oblique bending theory in the field of mechanics of materials. Investigation results show that difference between moment of inertia of the rotor′s shape and heart of two-pole turbine generator is one of the main causes of this kind of runout behavior.
