一、前言本文概述最高运行速度为200～300公里/小时的高速旅客列车的制动问题。高速运输对制动提出了严格的要求。制动机作用必须有效,能够吸收聚积的热量而无过热负荷,并能把这些热量消散到周围环境中去。即使在恶劣的气候条件下也必须把制动距离保持在规定范围内。为了满足运转要求和保证安全,要求缩短制动距离。然而,减速度受到了轮轨之间存在的粘着和制动装置复杂程度的限制。因此,信号系统和车上的制动装置必须相匹配。
I. Introduction This paper outlines the braking problems of high-speed passenger trains with a maximum speed of 200-300 km / h. High-speed transportation puts forward strict requirements on braking. The brakes must work effectively to absorb the accumulated heat without overheating and dissipate the heat to the environment. Braking distances must be kept within specified limits even in harsh climatic conditions. In order to meet operational requirements and ensure safety, shortening the braking distance is required. However, the deceleration is limited by the presence of sticking and the complexity of the braking device between the wheel and rail. Therefore, the signaling system and the vehicle’s brake must be matched.
