摘要
研究并给出了由动态油膜力进行轴承负荷分配和轴系稳定性诊断的方法和技术。作为应用 ,对一台2 0 0 MW汽轮发电机组进行了轴承负荷分配、动态负荷和轴系稳定性的测试和诊断 ,得到了丰富和重要的结论。这种正向推理和反向推理相融合的稳定性诊断方法在
An effective method is given to diagnose the stability of the rotor system by using the characteristics of oil film force. As an example, the bearing load of a 200MW turbine generator is identified, and the load distribution, the dynamic load of the bearing and the stability of rotor system are tested and analyzed. The results have a practical significance on the stability and security of large turbine generator set. A system including software and hardware is developed to realize the pressure method.
