“…In [18] the vertical vibrations are analysed by a five degree of freedom lumped parameter model representing the car, compensating sheave, and counterweight with the machine drive system and controllers used in the laboratory experimental tests. In [19] the lateral vibrations of the compensating ropes due to the longitudinal vibrations of the compensating sheave and the rope winding shape around the compensating sheave are studied by developing a lumped mass-spring model to compare with experimental results. In [20] a simplified calculation method based on a single degree of freedom system to predict the lateral displacements of the suspension and compensating ropes has been developed.…”

International Journal of Mechanical Sciences. 137, It is advisable to refer to the publisher's version if you intend to cite from this work. In a high-rise elevator system lateral vibrations of the suspension and compensating ropes, coupled with vertical motions of the car and counterweight are induced by the building structure motions. When the frequency of the building coincides with the fundamental natural frequency of the ropes, large resonance whirling motions of the ropes result. This phenomenon leads to impacts of the ropes on the elevator walls, large displacements of the car and counterweight making the building and elevator system unsafe. This paper presents a comprehensive mathematical model of a high-rise elevator system taking into account the combined lateral stiffness of the roller guides and guide rails. The results and analysis presented in the paper demonstrate frequency curve veering phenomena and a wide range of resonances that occur in the system. A case study is presented when the car is parked at a landing level where the fundamental natural frequencies of the car, suspension and compensating rope system coincide with one of the natural frequencies of the high-rise building. The results show a range of nonlinear dynamic interactions between the components of the elevator system that play a significant role in the operation of the entire installation.Crown

“…Kimura also proposed a simplified calculation method that replaces the wave equation with a single-degree-of-freedom system model [10]. As other methods for calculating the vibration response of elevator ropes, Hashimoto proposed a method using the finite element method [11], and Nakazawa et al proposed a method using multi-body dynamics [12]. Nguyen et al obtained the response of ropes by numerical analysis using the Newmark-β method and developed a control method for rope vibration [13].…”

Wire rope is an element often used in transportation infrastructure and systems such as bridges, elevators, ropeways, funiculars and so on. Generally, wire ropes require a high level of safety because they suspend heavy and important components such as roadways in bridges, cages and cabins in elevators, ropeways and funiculars. In addition to dead loads like roadways, wire ropes are subjected to dynamic loads caused by earthquakes, wind and moving cars, etc. Therefore, it is important to accurately simulate the dynamic response of wire ropes to dynamic loads to ensure safety of wire ropes. This paper deals with techniques for vibration response analyses of wire ropes. Techniques in this paper specially focused on a transverse vibration of wire ropes for elevators because their response is complicated by the moving cage and tension distribution. Vibration response analysis techniques using the difference method and a simplified mass point model will be introduced in this paper.

“…The centralized mass discretization model is mainly equivalent to the mass-spring-damping system with variable parameters. [10][11][12][13][14] The multi-degree-of-freedom lumped mass-spring model is generally established to calculate and analyze the vibration. The distributed mass continuum model is that the steel wire rope is equivalent to the extensible beam structure or the mass-loaded axially moving string with variable length and tension.…”

Horizontal vibration of a high-speed elevator can seriously influence the safety, stability, and ride comfort of the elevator during the operation. The construction of an accurate and robust dynamic model for horizontal vibration is the key to vibration control and suppression. In this article, the modeling and influencing factor analysis of the horizontal vibration of the high-speed elevator car are performed considering multi-component coupling. The rigid flexible coupling of the traction ropes and the elevator car system, the rigid irregularity perturbation generated by the manufacturing and installation errors of the guide rails, and the vibration inconsistency between the elevator car and car frame are considered in the modeling process. Based on the coupling system of the traction rope, elevator car, elevator car frame, guide rails, and rolling guide shoes, the kinematic horizontal vibration equation is established by using the generalized Hamilton’s principle. The solution of the horizontal vibration of the elevator car is derived based on the Galerkin method and MATLAB/Simulink software, and the influence of the perturbation frequency, irregularity perturbation type, and operating velocity on the horizontal vibration of the elevator car is analyzed. The KLK2 high-speed elevator is taken as a case study. Compared with the measured data, the mean absolute percentage error (MAPE) of the proposed model for maximum peak-to-peak (max [Formula: see text]) and [Formula: see text] peak-to-peak ([Formula: see text] [Formula: see text]) of the horizontal vibration acceleration is 6.08% and 5.16%, respectively, while the MAPE of a four degree-of-freedom model for the two is 16.74% and 7.35% and the MAPE of a distributed-parameter model for the two is 10.66% and 6.97%, respectively. The effectiveness of the proposed model is verified.
