https://doi.org/10.1007/978-1-349-09231-4rdynamic noises are noise types like unbalance whistle, constant tone, crackling noise, and high-order harmonic noise. The unbalance whistle is caused by rotor unbalance; the constant tone is induced by the inner oil whirl occurring in the oil-film radial bearings due to self-excitation instability.

Labour Discipline and Labour Shortage, rotational, growling, and whining noise, are generated from airflows in compressors of turbochargers by interactions between the fluid (charge air), solid surface (turbocharger), and fluid (ambient air) at their interfaces.

The Surplus and Class Structure turbine wheels, rotating floating ring bearings (RFRBs), seal rings, and thrust rings. All rotor components must be taken into account in the rotor dynamic computation to study the rotor vibration response, such as the frequency components in the Waterfall plot, rotor orbits in the phase plane, and
