20.500.12556/RUL-155748 Forced vibration of time-varying elevator traction system Vsiljene vibracije časovno spremenljivih dvigalnih pogonskih sistemov This paper proposes a theoretical model for the forced vibration of time-varying elevator traction systems caused by eccentric excitation of the traction machine. Based on the Hamilton principle and a variational principle with variable boundaries, the equations of motion and the complex boundary condition of a time-varying elevator traction system are established. A quantitative formula between the angular velocity of the traction machine, the diameter of the traction wheel, the elevator running distance and the running time is put forward. It is found that when the maximum values of acceleration and deceleration exceed 1.5 m/s², the elevator traction system may undergo resonance. elevator traction system vibration time-varying dynamics numerical analysis dvigalni pogonski sistem vibracije časovna spremenljivost dinamika numerična analiza pojav Hamiltonovo načelo Galerkinova metoda true false true Angleški jezik Slovenski jezik Članek v reviji 2024-04-15 10:26:34 2024-04-15 10:26:36 2024-04-16 03:45:05 0000-00-00 00:00:00 2024 0 0 Str. 170-180 no. 3/4 Vol. 70 Mar.-Apr. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 531.3:519.62:621.8 0039-2480 10.5545/sv-jme.2023.852 192497667 Sun..-Forced_vibration_of_time-varying_elevator_traction_system.pdf Sun..-Forced_vibration_of_time-varying_elevator_traction_system.pdf 1 981E10107B998FCF1F85270D5C62F540 89d8de6f9a4b0dde7d8eb326bce175441ef89f74984a3b860303b6f0fa699ca4 1c22a6b5-fb02-11ee-a0f3-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182811 https://www.sv-jme.eu/sl/article/forced-vibration-of-time-varying-elevator-traction-system/ 1 e4db1eac-fb01-11ee-a0f3-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182810 Fakulteta za strojništvo Strojniški vestnik 0 0 0
