Abstract
Recently, high speed elevators are strongly desired. But generally, it causes the increase of the deformation and vibration of the traveling cable. In a bad case, it collides with the side of the cage or facilities in the shaft, but studies about the traveling cable are very few. Behavior analysis of the traveling cable sway by the finite element method (FEM) was conducted and the validity of the analysis was confirmed. However, it took long time, so the analysis by multibody dynamics (MBD) is investigated in this paper. Good results were obtained by visco-elastic modeling with temperature dependent parameters. Furthermore, the collision analysis of traveling cable was conducted by MBD and the validity of the proposed analysis was confirmed through experiments using short length real cable.
