Analysis of the use of braking systems on high-speed rolling stock

This paper examines promising areas for the development of braking systems for high-speed trains using eddy current braking. The relevance of the study is driven by increasing rail speeds and the need to improve the safety, energy efficiency, and reliability of braking systems. Eddy current braking, based on electromagnetic induction, is a promising alternative to traditional friction and rheostatic systems, as it reduces wear on mechanical components and improves braking smoothness.

The research methods are based on a literature review of modern experimental studies on the use of various types of braking systems in high-speed transport. Particular attention is paid to combined systems combining eddy current braking with other technologies.

The results demonstrate the need to modernize existing braking systems to meet modern safety and energy conservation requirements. Key development areas are identified, including optimization of eddy current brake design, integration of energy recovery systems, and the use of new materials to improve efficiency.

The practical significance of this research lies in its proposal of specific solutions for the implementation of eddy current brakes on high-speed rolling stock. Implementation of these developments will improve rolling stock reliability, reduce operating costs, and ensure compliance with international safety standards. The results can be used in the design of new rail transport models.
