摘要

鉴于振动研究在电力工业生产中的重要地位

总结了国内外汽轮发电机组轴系振动近期研究进展

并对轴系振动研究的方法和发展趋势进行了分析和预测。分析认为:最近几年来

国内外对汽轮发电机组轴系振动的研究主要集中在转子预平衡、渐进式弯曲振动治理、机网耦合扭振、防旋汽封、弹簧隔振、转子裂纹、碳化摩擦等方面;未来

汽轮发电机组轴系振动研究的热点将集中在汽流激振源的精确定位、弹簧基础的动力优化、复杂结构的振动治理、次同步谐振等方面。

Abstract

Since the study on vibration has played an important role in electrical power generation

the achievements about vibration study on turbo-generator shaft system are summarized in recent years

and the development trend was predicted in this research area.In recent years

the general research interests are focused on the rotor pre-balancing

gradual rotor bend treatment

torsional interaction of the units with power systems

anti rotary steam sealing

spring vibration-isolation foundation

cracked rotor

rubbing vibration caused by bearing oil carbonization

and so on.In the future

the hotspots of vibration study on turbo-generator shaft system will focus on the steam-flow exciting vibration sources

spring vibration-isolation foundation dynamic optimization

complex structure vibration treatment and subsynchronous resonance.
