Taking a huge turbogenerator set as its background, this paper discusses the vibration analysis of such a system by using the impedance matching method, combined with the Riccati transfer matrix method and modal analysis, and satisfactory results are obtained. The methods, as shown by calculations, have the advantages of simplicity, practice and flexibility. In addition, the interrelations between the natural frequencies of the whole system and of the subsystems (rotor, foundations, etc. ) are easily revealed...

Taking a huge turbogenerator set as its background, this paper discusses the vibration analysis of such a system by using the impedance matching method, combined with the Riccati transfer matrix method and modal analysis, and satisfactory results are obtained.
