20.500.12556/RUL-132477 Multi-parametric dynamic analysis of a rolling bearings system A method for calculating amplitudes and constructing frequency characteristics of forced and self-excited vibrations of a rotor-fluid-foundation system on rolling bearings with a non-linear characteristic based on the method of complex amplitudes and harmonic balance has been developed. Non-linear equations of motion of the rotor-fluid-foundation system are derived, and analytical methods of their solution are presented. Frequencies of fundamental and ultra-harmonic resonances are determined. The intervals between self-oscillation frequencies are estimated. The dependence of amplitudes on the amount of fluid in the rotor cavity, the mass of the foundation, linear imbalance, the value of the stiffness coefficient, and the damping coefficient is shown. forced vibrations resonance fluid rolling bearing self-oscillations ultra-harmonic vsiljena nihanja resonanca tekočine kotalni ležaji samovzbujena nihanja ultra harmonična nihanja true false true Angleški jezik Slovenski jezik Članek v reviji 2021-10-27 08:46:46 2021-10-27 08:46:48 2025-03-07 13:27:07 0000-00-00 00:00:00 2021 0 0 Str. 421-432 št. 9 Letn. 67 Sep. 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.822.6:534.83 2536-3948 10.5545/sv-jme.2021.7178 79699715 RAZ_Kydyrbekuly_Almatbek_2021.pdf RAZ_Kydyrbekuly_Almatbek_2021.pdf 1 BDC46DE12D882FC402D568FA2FC0EBA9 a48e334676bd56ba9ea4f6079a146667be9fd7ec4462963c9a5069a437415767 d70002dd-36f1-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=150122 https://www.sv-jme.eu/sl/issues/issue-9-volume-67-2021/ 1 a2013390-36f1-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=150121 Fakulteta za strojništvo Strojniški vestnik 0 0 0
