UIC气动制动装置在长货运列车中的普遍使用可能涉及沿车队沿着施加制动力的时间延迟。这种沿列车沿着变化的制动作用可能导致沉重的纵向作用力，这可能导致货车损坏，甚至导致列车脱轨。这些现象的模拟是非常重要的安全和经济的原因，因为更长的货运列车意味着更高的运输成本降低。在本文中，作者提出了简化模型，用于评估，在一个方便的省时的方式如何列车组成，缓冲器的机械特性，制动装置的设计和其他关键参数可能会影响车队的纵向行为。
The common use of UIC Pneumatic braking plant in long freight trains may involve time delays in the application of the braking forces along the convoy. This variable braking action along the train may cause heavy longitudinal efforts that could lead to wagons damaging and even cause train derailment. Simulations of these phenomena are very important both for safety and economic reasons since longer freight trains imply higher transport costs reductions. In this paper authors present simplified models used to evaluate, in a convenient time-saving way how train composition, buffers mechanical features, braking plant design and other key parameters may influence the longitudinal behaviour of the convoy.
