3409 Vibration Analysis of Outdoor Elevator Rope : On the Improvement of Reliability under Strong Wind

Abstract

The lateral vibration of outdoor elevator ropes, which is excited forcibly by wind forces, is numerically analyzed, and a new practical method for reducing the rope vibration by using vibration suppressor is proposed. Finite difference analyses of the rope vibration with or without vibration suppressor are performed by considering the time-varying length and the tension distribution of the rope. The advantage of using the vibration suppressors for reducing the rope lateral vibration is demonstrated through the numerical calculation.
