RAMS在城市轨道交通牵引系统设计中的应用

摘要

城市轨道交通牵引系统的RAMS（可靠性、可用性、可维护性和安全性）特性，在牵引系统的设计开发中具有非常重要的作用。介绍牵引系统的基本组成以及影响系统RAMS的因素，从需求定义、系统设计、设计与实现、实施与制造、测试与验证、安全证据及交付这6个阶段简单描述了 RAMS实施的过程。%RAMS (reliability, availability, maintainability and safety) of urban rail transit traction system, plays a very important role in the design and development of traction system. Traction system of basic composition and effect of RAMS system factors are introduced and described, including the six stages from requirements defi nition, system design, design and implementation, implementation and manufacturing, testing and validation, and security evidence and delivery of RAMS in implement process.
