Abstract: Aiming at the research of the aerodynamic characteristics of super highspeed elevator, the models of 2Dhoistway, 3Dhoistway and 3Dhoistway with land sill were compared and studied at the velocity of the 10 m/s elevator. Aerodynamic characteristics was analyzed in different hoistway models through the ANSYS, which airflow distributions were got and compared in each hoistway models, which the airflow velocity curves were built at the lines in the symmetrical hoistway section and the velocity values were analyzed at the front and back side hoistway, which the maximum airflow velocity was built and compared in each line in the symmetrical hoistway section, which the influence of elevator aerodynamic force by the land sill was analyzed in the two models of 3Dhoistway. The results indicate that analysis has got the bigger airflow velocity overall which maximum airflow velocity is increased nearly 25%, and the air influence from the leftside and rightside cannot be attained in the 2Dhoistway model. In the 3Dhoistway models, land sill caused the incremental of the air velocity at the backside hoistway and decremental at the frontside hoistway, and the resistance force of the elevator car is increased nearly 93.2% and the overturning force was increased nearly 566.7%.
