| 摘 要： | 大型汽轮发电机组稳定性影响因素中,标高是非常重要的一个因素,轴系的振动特性是其主要指标,振动的大小又受载荷分配的影响,而标高的确定又影响着轴承载荷的分配。利用传递矩阵法计算轴系的标高,并结合某1 000MW机组对轴承载荷对标高变化灵敏度进行分析。

| Abstract: | Among all the factors influencing the stability of large-scale turbo-generator sets,the elevation is a very important one,the vibration characteristics of bearing system are its main indicator,and the elevation also influences the distribution of bearing load.The bearing elevation is calculated based on transfer matrix method.According to a 1000 MW unit,the sensitivity of bearing load to elevation variation is analyzed. |
