In the high-speed elevator,the sharp increase of car motion resistance and various eddy losses bring hidden dangers in system economy,safety and comfort.To analyze the aerodynamic characteristics of the flow field at the outer edge of the car,a numerical model based on computational fluid dynamics was established,and a mesh was dynamically generated by elastic fairing combined with local reconstruction method,and the high-speed elevator car with different fairing shapes(triangular,trapezoidal,elliptical and front fairings)was simulated.The results show that the installation of the fairing can effectively improve the flow field distribution and reduce the resistance coefficient of the car.The difference in the influence of different fairing shapes on the aerodynamic characteristics of the outer edge of elevator car is significant.Compared with the traditional symmetrical fairings,the front fairings have better performance with the resistance reduction ratio up to 80.21％.
