THE FEATURES OF THE POWER SCHEME OF THE NEW ELECTRIC LOCOMOTIVE 3ES5К (ERMAK) OF THE PARK OF UZBEKISTAN

The paper analyzes the characteristics and features of the traction chain of the 3ES5K electric locomotive. The design features of the electric locomotive are noted. A comparative analysis of traction and energy indicators with an electric locomotive of the VL80s series is carried out. Based on the results of the analysis, the indicators of energy consumption and running time on the existing section of Angren-Pap with the same mass of the train were derive

MODERNIZATION OF THE CRATE SUSPENSION UNIT OF THE VL-80S ELECTRIC CARRIER

The article presents the development of a modernized design of a cradle suspension unit for an electric locomotive VL-80s with improved elastic-dissipative suspension properties with substantiation of dynamic and strength parameters. Numerical studies were carried out in the MathCAD 15 programming environment. For railway company is necessary to develop a new method of modernizing the cradle suspension of the VL-80s electric locomotive during overhaul repairs in order to improve the dynamic characteristics and increase the strength and reliability
