Method for estimating the vibration shape of a 200m elevator rope with a single sensor

SPIE Smart Structures and Materials + Nondestructive Evaluation
In recent years, skyscraper construction has spread worldwide, and elevators have become increasingly important as a result. In an earthquake, an elevator cannot operate because the elevator ropes resonate with the building sway and swing wildly.

Novel robust controller design for load sway reduction in double-pendulum overhead cranes

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2018
It is seen that when the hook mass is larger than the load mass or the load has distributed mass property, the load sway of the crane system presents as double-pendulum effect. In this situation, crane system has two different natural frequencies so that
