The article provides brief description of a technical project for reequipping the electric locomotives VL80? and VL80S with smooth thyristor adjusters of tractive motors with the single automatic control system.

Purpose. When locomotives move in curved sections of the railway track, horizontal forces arise, which lead to pressing the ridge of the wheel pair to the railway track. The article is aimed to develop a method for determining the frame force acting on th... see more

The possibility of construction of a steady natural vibration system by introduction of successive correction link as an aperiodic link of the first-order is considered. 

At present, one of the main problems arising from the long-term operation of one-section electric locomotives is the need to maintain their good technical condition. In this case, the determining aspect is often rapid identification of existing defec... see more

The article describes the model of vibrations of an  electric locomotive ChS4. A vehicle is considered as a mechanical system of 9 rigid bodies (a body, 2 bogie frames, 6 wheelsets). 

The statistical analysis and probability characteristics of voltage random variation on the pantograph of DC electric locomotive in the recuperation mode are presented in the article.

The article is a continuation of analysis of the electric equivalent AC circuit «traction substation - device of transversal compensation  - electric-traction network  - electric locomotive DS 3» and the influence on a power  transformer in... see more
