Experiments on Rope Vibrations using a Small-Scale Elevator Simulator
- 발행 : 2014.10.29
초록
The elevator rope is easy to oscillate and continue vibrating because the rope structure is flexible and inner damping is small. The vibration of elevator rope is caused by the building vibration excited by external disturbances such as winds and earthquake. This paper is concerned with the experimental verification of the elevator rope vibrations using a small-scale simulator. The elevator rope vibration coupled with the building vibration was modelled using the energy method in the previous study. In this study, the natural frequencies of the elevator rope were computed using the theoretical model and compared to experimental results. Also, the time-responses of the rope vibration during the cage motion were measured by laser sensors and compared to the theoretical predictions. Experimental results are in good agreement with theoretical predictions.
