Scientific and technical outcomes development of high-speed electric train for Moscow – Saint Petersburg High-Speed Railway line

Introduction. The article addresses the principal scientific and technical challenges encountered in the design, engineering, and staged testing of the EVS360 high-speed electric train, developed for Russian high-speed railways. It presents the distinctive features of the technical solutions implemented in the traction electrical equipment and overall train architecture, and provides a substantiation of its key technical and operational characteristics.

Materials and methods. Numerical simulation methods were employed during the design phase of the high-speed electric train to determine its parameters and performance characteristics. Traction and braking dynamics along the track section were modeled using a computational approach grounded in the theory of traction, wherein the equations of motion were directly integrated over time. Aerodynamic analyses were conducted using turbulence models based on the eddy viscosity concept. Verification of the compliance of electrical equipment components with applicable regulatory requirements was performed through a series of mechanical, electrical, thermal, and other relevant tests.

Results. The principal outcomes of the scientific and technical project undertaken by JSC Russian Railways and JSC Engineering Centre of Railway Transport, aimed at developing a high-speed electric train, comprise a set of mathematical models, optimized technical solutions, design and manufacturing documentation for the electric train and its constituent components, prototype samples of products, as well as normative, technological, and operational documentation.

Discussion and conclusion. To date, a substantial volume of design, research, and development work has been completed toward the creation of a high-speed electric train for Russian HSR. Prototype samples of the primary traction electrical equipment components have been manufactured and are currently undergoing the requisite testing. In order to validate compliance with specified requirements and verify the calculated operational performance characteristics of the high-speed electric train, subsequent full-scale field tests are scheduled to be conducted at the Alabushevo – Novaya Tver experimental section of the first planned Moscow – Saint Petersburg HSR line.
