Abstract

A more accurate vertical dynamic model with nine degree-of-freedom (DOF) is proposed for better describing the vertical dynamics of high-speed elevator system. By developing a calculation program according to the proposed dynamic model, the dynamics behavior of a 2:1 high-speed roping elevator with rise over 24 meters is numerically calculated in empty load and full load cases at three landing positions: bottom, middle, and top floors. Under the test conditions identical with the simulation but without full load case, modal experiment is applied to an elevator having the same specifications as simulated one. The proposed model is confirmed by comparing numerical and experimental results, and both results indicate that the vertical dynamic characteristics of high-speed elevator are time variant. It is also presented that the low order frequency of high-speed elevator is not sensitive to the variation of hoist rope length but greatly influenced by passenger load.
