【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]:In view of the important position of vibration research in power industry production, the recent research progress of turbine generator shafting vibration at home and abroad is summarized. The research methods and development trend of shafting vibration are analyzed and forecasted. It is concluded that in recent years, the research on shaft system vibration of turbine-generator set is mainly focused on rotor pre-balance and progressive bending vibration treatment. Coupling torsional vibration of mechanical network, anti-rotating steam seal, spring vibration isolation, rotor crack, carbonization friction, etc. In the future, the research focus of shaft system vibration of turbogenerator will focus on the precise location of steam excitation source, the dynamic optimization of spring foundation, etc. Vibration treatment of complex structure, sub-synchronous resonance and so on.
