摘　　要：简述了某半转速核电汽轮发电机组的结构特点,建立了包括弹簧基础、转子轴系及轴承在内的轴系数学模型,并据此计算了轴系各加重位置一阶、二阶加重响应数据,对轴系不平衡响应特性进行了分析研究,为后续机组检修、现场动平衡提供参考。The structural characteristics of a half-speed nuclear turbine generator set are briefly described,and the shaft coefficient model including the spring foundation,rotor shafting and bearings is established.Based on this,the first-order and second-order weighted response data of each weighted position of shafting are calculated,and the unbalance response characteristics of shafting are analyzed and studied,which provides a reference for the follow-up maintenance and field dynamic balancing.
