Application of Digital Verification Technology in Brake System

As one of the key subsystems of train, brake system plays an important role in the development of railway. The test verification of the braking system is an important part of the research and development design; And it is the basis to ensure the safe operation of the train. Traditional test verification is mainly carried out by physical test bench, but it has the disadvantages of high construction cost, long construction period and needs to spend a lot of human resources. Digital verification is introduced into the development process of brake system because of its flexible and configurable advantages, which provides a new means for brake system testing and verification.This paper will mainly introduce the status of brake system test research, the application of digital verification technologies such as numerical simulation and semi-physical simulation in the field of brake system, and finally look forward to the verification methods of rail transit equipment in the future.
