THE AERODYNAMIC RESISTANCES DETERMINED BY THE ROLLING EQUIPMENT FOR THE ELECTRIC LOCOMOTIVE LE 060 EA 5100 KW

摘要

Depending of the construction of railway vehicle engine, the equipment of traction and rolling may have a lower or higher influence about the running resistance. This article aims an analysis of the aerodynamic resistance generated by these equipments of the locomotive LE 060 EA of 5100kW. In order to estimate the values of aerodynamic resistances generated by this equipments it was modeled geometric in 3D at 1:1 scale the chassis, the bogie frame and axle engines for locomotive. The ensemble obtained is used for simulation air flow on different values of speed of movement of the vehicle in the range of between 0km/h and 200km/h.
