Elevator traveling cables are forced to vibrate due to various causes such as the vertical and horizontal movement of the car, the vibration of the building caused by earthquakes, strong winds, etc. This paper discusses the dynamic characteristics of the cables with respect to the above factors using simulation analysis. The model cable used in the simulation consists of multiple rigid links which are serially connected by rotational joints made of spiral spring. As a result, the following conclusions have been obtained. (1) The shape of the cable changes to a large extent due to the vertical movement of the car. The magnitude of the cable vibration is not affected by the car speed or the cable length, but is mainly dependent on the car acceleration. (2) With respect to the horizontal vibration caused by the vibration of the car and building, a characteristic period of 2.5 seconds was obtained, with the cable length of 5.4 meters, from the response simulation. On the contrary, the results of the eigenvalue analysis differ largely from the above simulation in both frequency and mode. Therefore eigenvalue analysis is not effective in the study of cable vibration.
