The winds gusts with high speed can negative affect the operation of railway electric vehicles. These vehicles can achieve high performances, as long as the power supply is ensured, without discontinuities or interruptions in the process. This article is an analysis of how the wind gusts affect variation drag resistance to advancing caused by the pantograph and how they affect the supply of electricity required for vehicle movement. To this end, in a first step, we modeled geometrically in 3D EP3pantograph, which was raised to maximum working height. For simulation of air flow among the components of the collector (pantograph active) we considered how it is used and placed on the vehicle body. For analyze the effects caused by gusts of wind, we considered point values for angles within the range [0°, 180°] and speeds, a range of from 0m/s to 30m/s. This article is developed in programs postdoctoral studies at the University Politehnica of Bucharest.
