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 0 m/s to 30 m/s. This article is developed in programs postdoctoral studies at the University Politehnica of Bucharest.

The test stand for electric motors is intended to test electrical machines used in railway traction. The stand is the result of a research contract with the realization and implementation practice in SC Remarul February 16 SA-Cluj. The stand is designed for tests to verify the maintenance of technical parameters (mechanical and electrical) and verifying proper operation of electrical machines used in railway traction. The stand includes a modern acquisition, display and data storage for the main parameters measured, the software being developed in Visual Basic.

One of the elements of the load-bearing structure of the railway vehicles is the bogie. This element is allowing the link between the chassis on which the vehicle box and the rolling elements (axles, wheels) by means of the suspension elements. Depending on the type of vehicle where the bogies (motors vehicle or towed vehicle - wagon) are used, its static and dynamic loads differ. On motors vehicles, the axle drive system additionally loads the vehicle structure (bogie or chassis) into there are fixing points. Depending on the type of drive system used, the distribution of the forces and moments generated by the drive equipment at the axles is different. For the case of the LE 060 EA locomotives, which is mostly used by the Romanian railway operators, the drive system is individual, with the suspended electric motor and the semi-suspension reducer (supported on the axle and connected to the bogie frame). This paper aims to analyse the load rating of the bogie frame, taking into account the type of drive system used to transmit the traction force to the motors axles of the vehicle. In this respect, it was modelled in 3D format at scale 1: 1, the bogie frame of the LE 060 EA locomotives.
