联接刚度对核电百万千瓦级汽轮发电机轴系的动力特性影响研究

STUDY ON INFLUENCES OF CONNECTION STIFFNESS ON THE DYNAMIC FEATURES OF MILLION-KILOWATTS-CLASS NUCLEAR POWER TURBOGENERATOR SHAFTING

Reduce分析法可大为简化联接刚度对核电百万千瓦级汽轮发电机轴系的动力特性影响之研究。在自行研制的“核电百万千瓦级汽轮发电机轴系模拟试验台”上,成功地进行了联接刚度对轴系固有频率的灵敏度分析,为“核电百万千瓦级汽轮发电机”的动力修改奠定了坚实的基础。

It is much more simplified to study the influences of connection stiffness in shaft system for the million - kilowatts - class nuclear power turbogenerator by the Reduce - Analysis method. Using the Reduce - Analysis method and “the self - designed test set of the million - kilowatts - class nuclear power turbogenerator shafting”,the sensitivity of the connection stiffness to the shafting natural frequency is analysed successfully,and the solid basis of the dynamic modification is built for the million - kilowatts - class nuclear power turbogenerator.
