Due to the tunnel aerodynamic effect,the aerodynamic resistance of high-speed elevator has a great influence on the smooth operation of the lift car.It is found in engineering studies that the geometric structure of the lift car and elevator well is an important factor affecting the aerodynamic resistance of the elevator.In this paper,the computational fluid dynamics(CFD)method is adopted to study the main factors affecting the aerodynamic resistance of high-speed elevators,and the aerodynamic performance of the lift car is improved by designing the aerodynamic additional device,and the effectiveness of the improvement is verified by simulation.It provides an effective tool for the design and development of high-speed elevator.
