摘要：

A twelve-degrees-of-freedom nonlinear vibration model of the elevator cabin-rail coupled dynamic system is established based on the appropriate analysis of the cabin-rail coupled dynamic system. The numerical iterative solution method using the state-space approach is described. The properties in both time domain and frequency domain of the horizontal vibration of elevator cabin under different running conditions, such as the variation of the excitation intensity of rail irregularities or the variation of velocity, are explored. The exploration provides an important theoretical foundation for determining the reasonable tolerances of the guide rails in assembling. In the mean time, the result is helpful for impelling the studies on optimization of the cabin structure and vibration control of the cabin system.
