The Summary Research on the Noise of High-Speed Traction Elevators

Abstract

With the increasing of speed of elevator, noise has been becomming an important factor of the ride comfort. Mechanical noise and aerodynamic noise are the main types of elevator noise. The research of mechanical noise are mainly focused on vibration characteristics of the structure and the friction which is on elevator cars, counterweight and guide rails as well as wire ropes. The research of aerodynamic noise are mainly included three aspects: the influences of aerodynamic noise resulted in the shape of elevator cars, the research of noise reduction technology on different noise bands and the research of elevator system dynamics model’s optimal design. Based on the analysis of high-speed elevator noise research, we investigate the existing problems and trends on high-speed traction elevator noise.
