This paper has mainly studied the analysis and application of torsional vibration for centrifugal compressor trains, including static and transient torsional analysis and engineering case. The static torsional analysis comprises torsional eigenvalue problem, Campbell diagram, torsional resonance analysis method based on modal superposition method, and calculation and evaluation method for torsional stress, etc. The transient torsional analysis includes transient torsional excitations of electric motor driven units, analysis and evaluation for transient response. Emphasis is put on the linear integer harmonic and nonlinear interharmonic excitations of VFD driven units, as well as the subsequent analytical approaches.
