Research and Design of Brake Problem Solving System for Electrical Vehicles
Abstract：In the design and operation management of rail transit system, train brake is a very important and complex problems, it not only relates to the safety, and related to the transport capacity of the train. The electric vehicles is an important part of the rail transit system, in this paper, the brake problem of different electric locomotive is studied. Train brake problem solution is the core of braking distance calculations, to complete the calculation of braking distance first to know the force when the train braking. For intuitive and clear understanding of the force condition with different vehicle under different conditions , this topic by using MATLAB GUI design a simple interface to calculating electric locomotive braking problems, and through the concrete example to verify this system. The research results can provide the analysis of the electric locomotive brake problems with the corresponding help.
Key Words：Electric vehicles; unit composition forces; braking ratio; braking distances
