Research on the Construction of Hardware Reliability System of Electronic Equipments for Rail Traffic Vehicles

Reliability engineering is a science and technology to fight against product failure, which includes reliability requirements and allocation, reliability analysis, reliability modeling and prediction, reliability design, reliability test, reliability testing, operational reliability and other activities. The important condition for the high-quality development of rail traffic is the stable operation of equipment, and the electronic equipment of rail traffic vehicles is mostly the “brain” of the key system. At present, the contradiction between performance optimization and structural complexity is increasingly prominent. In order to cope with the variable operating conditions and harsh environment of vehicles, the requirements for reliability are getting higher and higher. It is of great significance to carry out reliability engineering for its high-quality development. This paper introduces the construction of the reliability system of the electronic equipment of rail traffic vehicles, discusses the guiding ideology of the construction of the electronic equipment reliability system based on the actual situation, expounds the content of the reliability system from three aspects: management system, technical system and resource system, and introduces each reliability activity in detail and with emphasis based on the practical application experience. Combined with the experience and lessons, the paper puts forward some suggestions on the construction of reliability system.
