- The pressure correction method based on N-S equation, using the split SIMPLE algorithm, the crosswind conditions of pantograph's aerodynamic characteristics numerically simulation analyzed. The results show that with the wind direction increasing, the pantograph's aerodynamic load is nonlinear, the lift coefficient increases with the increase of wind angle; at the same time as the wind speed increases, the slope of lift coefficient increases; pantograph overturning moment, cornering coefficient increase as wind direction angle increases. The lateral force coefficient increases monotonically with wind direction angle increases; to flow around the contact wire and slide, slide bracket, forming a large area in the rear of the slide wake zone near the leeward side, small scale in the slide and contact line vortex accounted for the major part, while the two slide end and separate the vortex interaction support And the results can provide a basis for improving stability and safety of the pantograph of the crosswind.
