Free vibration analysis of a string with vibration suppressor located at 1/N of the string (When N is an even number)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
When an elevator rope for a high-rise building is forcibly excited by the displacements of the building induced by wind forces and/or by long-period ground motion, rope displacement becomes large even if the ground acceleration and the buildings ...

Free vibration analysis of string with vibration suppressors located in center part of string

open access: yesMechanical Engineering Journal, 2016
Vibration suppressors are used to change the natural frequency of an elevator rope and prevent resonance. The displacement of the parts of the elevator rope at both the ends is small compared to that of the center part of the rope; therefore, it is not ...
