“…Various methods have been used in elevator vibration reduction. Active control methods, such as PID control, 9 modal control, 10 and adaptive control, 11 utilize feedback or feed-forward control to offset or compensate for vibration sources or perturbations on the transmission path. Furthermore, passive control methods have been studied extensively to optimize the design of component structures, including the size and performance parameters of elastic or damping elements, in order to minimize vibration and achieve balance in the elevator car.…”

The horizontal vibration of high-speed elevators has a significant impact on ride comfort and safety stability. Plenty of intelligent methods have been implemented in horizontal vibration reduction. The conventional optimization process for vibration reduction design involves conducting numerous complex dynamics simulations to establish the correlation between design parameters and vibration response. However, this method is inefficient and costly due to the demanding computational power requirements and time-consuming nature of the simulations. This study proposes a surrogate-model-based dynamic-sensing optimization method. A Kriging model is developed based on dynamics simulations, providing an efficient approach for obtaining the vibration response with specified design parameters. The DSPSO algorithm was proposed by incorporating perceptual particles and environmental adaptation mechanisms into the PSO algorithm. The DSPSO algorithm can be nested and interact with the Kriging model to optimize design parameters. During evolution, feasible and uncertain solutions are extracted into the sample space to enhance the accuracy of the Kriging model. The effectiveness of the proposed method is validated using both the ZDT series test functions and elevators from Canny Elevator Co., Ltd.

“…In order to reduce the impact of the guide rails, the car is "suspended" on them. The electromagnetic active rolling guide shoes can exert active control force through electromagnetic force, which can separate the car from the guide rails and reduce the impact of the uneven guide rails on the car [14]. This structure can also be easily added to the traditional guide shoes of the elevator.…”

Aiming at the problems of inefficient mitigation of the lateral vibration of high-speed elevator cars, which results in low riding comfort, this paper introduces the electromagnetic active rolling guide shoes and incorporates the sky-hook damping control strategy into the high-speed elevator structure. On this basis, it adopts an optimization algorithm based on Sparrow Search Algorithm (SSA) to adjust the parameters of the lateral vibration controller, thereby reducing the amplitude of the lateral vibration and controlling it within the human comfort range. Specifically, this paper first incorporates electromagnetic active rolling guide shoes into the vibration reduction device of the high-speed elevator car. Based on the motion characteristics of lateral vibration, a mathematical model is established in which the sky-hook damping control strategy is introduced. Then, a simulation model is built, and the damping parameters of the controller are optimized using the SSA, resulting in effective control of the lateral vibration amplitude of the high-speed elevator car. Simulations demonstrate that the lateral vibration control model of the high-speed elevator car, optimized by SSA, achieves lower amplitudes within the frequency range of 1–2 Hz compared to the results obtained by the Genetic Algorithm (GA), demonstrating the effectiveness of SSA in optimizing the damping parameters of the car controller. Finally, the simulation results are compared with the measured data, and the research findings indicate that the proposed method for lateral vibration control of the car can effectively suppress the lateral vibration amplitude.
