摘　　要：为了提高机组安全运行,轴系振动特性设计是减少机组振动的主要途径。文章介绍了大型汽轮发电机组轴系临界转速、不平衡响应、共振转速峰值响应灵敏度(Q因子)和轴系扭振的研究。通过轴系动态振动特性计算,使大型机组轴系具有良好的振动特性。In order to improve the safe operation of steam turbinegenerator wnit,the characteristic desingn of shaft system vibration is the main way to reduce the vibration of unit. The paper introduces the researches on the critical speed,response of unbalance,response sentivity Q factor of resonant speed peak value and torsional vibration of large size steam turbinegenerator unit shaft system. The dynamic characteristic calculation of shaft system can make the shaft system of large size units to have good vibration characteriaties.
