A computational investigation of the disk-housing impacts of accelerating rotors supported by hydrodynamic bearings,

Original language description

As the radial clearance between discs and the casing of rotating machines is usually very narrow, excessive lateral vibration of accelerating rotors passing critical speeds can produce impacts between the discs and the housing. In the developed procedure, the shaft is flexible and the discs are absolutely rigid. The hydrodynamic bearings and the impacts are implemented in the mathematical model by means of non-linear force couplings. Most of the publications and computer codes from the field of rotor dynamics are referred only in the case when the rotor turns at a constant angular speed and in simple cases of disc-housing impacts. Moreover, if the discs turning at variable speed are investigated, the resulting form of the equations of motion derived bydifferent authors slightly differs and the differences depend on the method used for their derivation. Therefore particular emphasis in this article is given to the derivation of the motion equations of a continuous rotor turning with va
