Abstract:

With the continuous improvement of high-speed traction elevator speed, noise has become an important index of ride comfort. Vibration noise and aerodynamic noise are the main sources of elevator noise. The research of vibration noise mainly focus on the reduce of the resonance，the friction between elevator cars and counterweight and guide rails and wire rope. The researches of aerodynamic noise mainly include the following three aspects: first, the research of the elevator cars’shape on the effects of aerodynamic noise; Second, the research of noise reduction technology on different noise bands; Third, the research of elevator system dynamics model’s optimal design. Based on the analysis of high-speed elevator noise research, we investigate the research trends of the high-speed traction elevator noise.
