Free vibration analysis of a string with vibration suppressor (When the position of vibration suppressor is opposite to the pulled position)

Mechanical Engineering Journal, 2016
A vibration suppressor is used to change the natural frequency of an elevator rope, and to prevent resonance. The elevator rope is modeled using a string.

Vibration analysis of elevator rope with one vibration suppressor

Nihon Kikai Gakkai ronbunshu, 2018
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 ...

Vibration analysis of elevator rope with vibration suppressors (When vibration suppressors are uniformly installed or uniformly installed except for both ends part)

Nihon Kikai Gakkai ronbunshu, 2019
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 ...
