Abstract: The instantaneous variation of pressure loads acting on the rotors of positive displacement rotary blowers may produce vibrations and noise that in some case produce the failure of the machine ...

Abstract: In the field of rotor balancing, the traditional influence coefficient method is often employed along with weighted least squares in order to reduce amplitude vibrations, typically at selected ...

Abstract: Rotating machines that include geared shaft-trains can be affected by a dynamic behavior that is influenced by coupling effects between lateral and torsional vibrations. These latter vibrations ...

Abstract: The methods employed to perform rotordynamics calculations of industrial machines are rather standard and usually allow forecasting the dynamic behavior of the considered machines. Anyhow, in some ...
