This paper investigates the aerodynamic interaction between an elevator car and its counterweight during high-speed intersection using Computational Fluid Dynamics (CFD). The flow field characteristics are analyzed to evaluate the impact of aerodynamic forces on the stability and operational safety of high-speed elevator. A numerical model was established to simulate the intersection process, and key parameters such as lateral force coefficients and pressure distributions were derived. The proposed asymmetric fairing design, which redirects airflow from the car's windward side toward the non-counterweight side, effectively reduces lateral forces during car-counterweight intersection. The study reveals critical aerodynamic phenomena during intersection, providing insights for optimizing elevator design and mitigating instability risks.

摘要

This paper investigates the aerodynamic interaction between an elevator car and its counterweight during high-speed intersection using Computational Fluid Dynamics (CFD). The flow field characteristics are analyzed to evaluate the impact of aerodynamic forces on the stability and operational safety of high-speed elevator. A numerical model was established to simulate the intersection process, and key parameters such as lateral force coefficients and pressure distributions were derived. The proposed asymmetric fairing design, which redirects airflow from the car's windward side toward the non-counterweight side, effectively reduces lateral forces during car-counterweight intersection. The study reveals critical aerodynamic phenomena during intersection, providing insights for optimizing elevator design and mitigating instability risks.
