摘要

Abstract

In order to research the aerodynamic characteristics of the sinking pantograph under crosswind conditions,the finite volume model of pantograph and car body was es-tablished based on k-omega SST two-equation turbulence model by using the finite volume method.Analyzing the sinking pantograph as the research object,it focused on the surface pressure,velocity distribution,turbulence intensity and aerodynamic lifting force of the pantograph under open line and crosswind conditions,as well as in both open and closed operating directions.The results show that the complexity of air flow field under cross-wind condition is greater than that under no crosswind condition,and the instability and a-symmetry are more obvious.The static average contact force of the sinking pantograph in open operation is larger than that in closed operation.The static average contact force is close to the standard limit when the 200 km/h opening is operated and the crosswind speed is 25 m/s.
