摘　　要：分析了汽流激振的机理和振动特征,提出了对汽流激振应采取的对策,阐述了防止激振的设计准则和措施,介绍了国际各大制造厂对汽轮发电机组轴系稳定性的基本判定依据,并结合泰州1000MW机组工程设计阐述了防汽流激振及轴系失稳的措施。The mechanism and features of steam-excited vibration are analyzed in this paper. From adjusting the operation modes and improving the system damping etc.aspects,the inhibition measures of steam-excited vibration are given out. The design criterions as well as preventing measures of steam flow excited vibration are expounded. And the basic stability criterions of turbine shafting used by main manufacturers abroad are recommended. Solution of Taizhou Generation Co, Ltd 1000MW generating set in design is described briefly.
