Core technical advantages: First, full-scene aerodynamic simulation optimization, through computational fluid dynamics (CFD) simulation, simulate the aerodynamic characteristics of elevators under different speeds and different shaft sizes, optimize the car shape, shaft clearance, and ventilation structure, and reduce aerodynamic resistance and aerodynamic noise from the source; Second, car streamlined bionic design, adopting bionic streamlined car shape, setting fairings on the car top and car bottom, reducing airflow separation and vortex generation, reducing operating wind resistance by 30% and aerodynamic noise by 25%; Third, shaft pneumatic diversion system, set pneumatic diversion devices at the top, bottom and landing door of the shaft to balance the air pressure in the shaft, reduce the piston effect, and reduce the air pressure fluctuation and wind whistle during high-speed operation of the elevator; Fourth, active noise reduction system, set multi-channel active noise reduction array on the inner wall of the car, car top and car bottom, offset aerodynamic noise and mechanical noise through reverse sound waves, which can accurately offset noise of different frequencies, with the maximum noise reduction of 25dB; Fifth, vibration suppression optimization, through car aerodynamic balance design, guide rail guidance optimization, and vibration reduction system upgrade, reduce the pneumatic vibration during high-speed operation of the elevator. The vertical vibration acceleration of the car is ≤0.1m/s², and the horizontal vibration acceleration is ≤0.05m/s², which is far better than the national standard requirements.
