| 摘 要： | 电制动力和空气制动力配合是当今高速动车组和新型城市轨道交通车辆制动系统的主要制动方式.2型高速动车组(CRH2)的电制动力和空气制动力以一动一拖的编组为单位进行协调配合,不同制动工况下电制动力和摩擦制动力的组成方式多样.通过分析其结构和制动力构成的特点,运用旁联结构建立了编组制动系统的可靠性模型.根据相似产品可靠性数据,对所建立的可靠性模型进行了定量计算.

| Abstract: | Electro-pneumatic braking system is becoming more and more popular.Electric braking cooperates with pneumatic braking in a unit of CRH2 composed of one motor car and one trail car.There are various configurations for electric braking force and pneumatic braking force.So it gives difficulty in setting up the reliability model.This paper,presents an analysis for the configuration of CRH2 braking force.And the reliability model is set up with standby structure.After that,quantitative calculation is carried out... |
