On the other hand, the land resources of the city are precious, so the elevator shaft is generally designed to be narrow. The pneumatic characteristic of the elevator is further deteriorated, the pneumatic load borne by the elevator is increased, and the development of the ultrahigh-speed elevator in China is severely restricted. Therefore, in order to realize safe, comfortable and stable operation of the ultra-high-speed elevator, the pneumatic characteristic of the ultra-high-speed elevator and the pneumatic optimization design method thereof are researched, so that the improvement of the pneumatic characteristic of the elevator becomes more and more important. The air guide sleeve has an obvious effect on improving the pneumatic characteristic of the high-speed elevator.
Ultra-high speed elevators generally refer to elevators with a travel speed of more than 7m/s, and as the speed of the elevator increases, the pneumatic load on the elevator also increases sharply. An increase in the aerodynamic load leads to an increased effect of wind-induced vibrations of the elevator, which greatly reduces the ride comfort and the operational safety of the elevator. To improve this situation, the demands on the high-speed elevator dome are more stringent.
