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.

Free vibration analysis of a string with vibration suppressor located at center of the string (When there is a gap between string and vibration suppressor)

Nihon 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 a string with vibration suppressors located at 1/N from both ends of the string(When N is an even number and gap between string and vibration suppressor is not zero)

Nihon Kikai Gakkai ronbunshu, 2017
In high-rise buildings, the elevator rope may resonate with the building's sway induced by wind forces and/or by long period ground motion. Therefore, suppression of elevator rope vibration is desired. To gain an understanding of rope sway, the free

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

Nihon Kikai Gakkai ronbunshu, 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. Linear string vibration is well known.
