摘要
本文从大型机组轴系弯曲振动、汽流激振及扭振的角度出发,通过对上汽西门子独特创新技术的介绍,分析研究其单轴百万级超超临界汽轮发电机组轴系的稳定性及振动特性,为大型汽轮发电机组轴系振动特性设计及故障分析提供借鉴。
Based on the rotor vibration,shock excitation of steam flow and torsional oscillation of large-size turbine-generator units,and the unique and innovative technology of Siemens is introduced.Besides stability and vibration characteristics of turbine-generator shaft system are analyzed,which provide reference for the design of vibration characteristics and fault treatment of large-size units.
