“…Moreover, mathematical models to represent high rise elevators (Crespo et al, 2018;Fortgang et al, 2006), and specific parts of the elevator system such as the ropes (Kaczmarczyk et al, 2003) and the compensating sheave (Watanabe and Okawa, 2018) are found. The cabin has also been extensively studied because it is vulnerable to the vertical and the lateral vibrations that affect the passenger comfort (Coffen et al, 1997;Feng et al, 2009;Herrera et al, 2010Herrera et al, , 2014aQiu et al, 2020;Zhang and Yang, 2017).…”

“…The influence of both internal and external variables on the dynamics of the elevator system has also been assessed. Regarding the internal variables, the influence of the design parameters of the elevator (Qiu et al, 2020; Vladić et al, 2011) and the influence of random parameters caused by manufacturing and installation errors (Zhang and Yang, 2017) are studied optimizing the elevator system. In addition, external variables may also influence the behavior of the system.…”

The attenuation of the structure-borne sound caused by elevator systems in residential buildings is a priority for manufacturers. This work develops a model of an active control isolation system for the vibrations produced by the elevator drive machine. This solution proposes the substitution of conventional passive isolators by new ones made of a magnetorheological elastomer (MRE), a smart material whose modulus can be modified by applying a magnetic field. To guide the design process, MRE isolators are fabricated and experimentally tested statically and dynamically in compression mode. Subsequently, the parameters of the MRE are fitted to build a nonlinear material sub-model that accounts for the frequency, amplitude, and magnetic field dependency. Afterward, a global model of the elevator drive machine vibration isolation system is developed, which incorporates the drive machine, structure, and MRE-based isolator. To enhance vibration isolation, two active control strategies are designed and assessed. Simulation results predict that active control systems based on MRE isolators improve vibration isolation as compared to traditional passive systems. The excitation amplitude and frequency, along with the control strategy and magnetization of the MRE isolators are shown to be critical parameters when designing an active control solution.

“…In the course of operation, the car is influenced by a lot of uncertainties, such as irregularity excitation of guide rail, 11–14 airflow excitation, 15,16 rope swing excitation, 17–20 and so on, and all the uncertainties can be combined into, over centroid O , an X -direction excitation Fx, Y -direction excitation Fy, θx-direction excitation Fy, θy - direction excitation T y , and θz-direction excitation TZ. The control force of the actuator in the direction of X is Fcx and Y -direction is Fcy.…”

Due to the influencing factors, such as irregularity of guide, piston wind excitation in the hoistway, and uncertain swinging of hoisting rope during the operation of high-speed traction elevator, car will produce dramatic horizontal vibration. With the purpose of suppressing this vibration effectively, the active car shock absorber is designed with linear motor, and a five-degrees-of-freedom space vibration model of the car is established and, subsequently, its state space equation is derived. For the uncertainty external excitation in the car system, the back propagation neural network proportional–integral–derivative controller with linear prediction model is designed for the intelligent active control of the vibration of the car, and simulation analysis is carried out with MATLAB/Simulink. The result shows that the active shock absorber designed in this study can effectively suppress the horizontal vibration of high-speed elevator car, better than traditional proportional–integral–derivative controller. This study has opened up a new idea of high-speed elevator vibration damping method, and is of important referential significance for the field of active control of car vibration.
