Free vibration analysis of a string with vibration suppressors located at 1/N from both ends of the string (When N is an odd 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.

Lateral vibration estimation of an elevator rope by sequential modal decomposition of elevator rope displacement observed near the traction sheave

Nihon Kikai Gakkai ronbunshu
In high-rise buildings, elevator ropes, which are flexible long objects, continue to vibrate with very large amplitude for a long period of time during an earthquake. The elevator cannot be restarted unless this vibration is reduced.

Computational fluid dynamics modeling of rope-guided conveyances in two typical kinds of shaft layouts. [PDF]

PLoS ONE, 2015
The behavior of rope-guided conveyances is so complicated that the rope-guided hoisting system hasn't been understood thoroughly so far. In this paper, with user-defined functions loaded, ANSYS FLUENT 14.5 was employed to simulate lateral motion of rope ...
