Study on the mechanical properties of guide shoe on the transverse vibration of high-speed elevator

Abstract

The vibration of car systems in high-speed elevators is analyzed especially the mechanical properties of the rolling guide shoe. As a guiding mechanism, the rolling guide shoe plays a crucial role in car vibration. The mechanical properties of rolling guide shoes mainly include the dynamics of the guide shoe mechanism, emphasizing the complex multi-degree-of-freedom system vibration of the car-frame, as well as the nonlinear mechanical properties of the guide shoe lining rubber and guide rail contact. Taking the parameters such as guide shoe lining material and contact thickness into account a mechanical model for the guide shoe is established using the finite element method. To analyze the transverse vibration of the car-frame, an8-degree-of-freedom dynamic model is established using Lagrange equations. The Newmark numerical solution algorithm is used to study the impact of different mechanical parameters of guide shoes on the transverse vibration of cars. The results indicate that using a guide shoe with small stiffness and large damping can effectively reduce the transverse vibration of the elevator. The methodology and findings can provide valuable reference for the design of guide shoes for high-speed elevators.
