摘要/Abstract

摘要： 由于N+1支撑轴系结构特殊性，西门子1 000 MW汽轮机组轴系不平衡振动特性复杂，导致该机型在实际运行中经常出现振动故障。采用有限元法，根据机组基本结构尺寸，建立了轴系动力学模型，通过数值仿真计算了轴系临界转速和振型，分析了轴系上10个平衡位置加重后轴系额定工作转速3 000 r/min下涡动响应，比较得出轴系不同轴向位置加重对轴系振动的敏感程度和影响规律，从而为该型机组实际运行过程中的振动故障监测和诊断分析提供参考。

Abstract: Due to the structural particularity of N+1 supported shafting, the unbalanced vibration characteristics of Siemens 1 000-MW steam turbine units are complex, which is likely to lead to vibration faults in practical operation. In this paper, units, the shafting dynamic finite element model is built based on the basic structure parameters of the units by using the finite element method. The critical speeds and vibration modes of the shafting are calculated by numerical simulation., the shafting response at the speed of 3 000 r/min is analyzed by weighting the ten axial balancing locations on the rotor respectively. Then, the sensitivity and rules of the shafting vibrations are obtained by comparing the weights and the locations. The conclusion can help the vibration monitoring and fault diagnoses in the operation process of the steam turbine units.

Key words: 1 000-MW steam turbine unit, N+1 supported shafting, critical speed, unbalanced vibration characteristics
