Case Studies of Self-excited Vibration of Rotor Stability Problems,ional to the rotational speed. Therefore, self-excited vibration is a form of non-synchronous vibration. In rotor systems, the lowest natural frequency is often below the rated rotational speed and it may become unstable, hence self-excited vibration is also known as sub-synchronous vibration. This

Torsional Vibration and Related Coupled Vibration,able in geared rotor systems. Though torsional vibration poses long-term problems, new methods of rotor design have been established by employing the transfer matrix method, which are capable of calculating precisely the rotor vibrations according to the shaft configuration. However, several coupled

Signal Processing for Rotor Vibration Diagnosis,int of vibration, noted as“1X” or “1N” vibration. A vector monitor (R1_Fig. 5.8) is a measuring instrument including a tracking filter that extracts only the 1X vibration component from the actual vibration waveform. In this chapter, the principle and the application of this vector monitor are expla

Our Latest Topics Relating to Simplified Modeling of Rotating Systems,types of codes, 3D-FEM and 1D-FEM (e.g., MyROT introduced in R1_Chap. 12), are available for engineering design based upon multi-DOF (degree of freedom) modeling. However, case studies of vibration problems show the benefits for understanding the vibration mechanisms and their practical and potentia
