摘要:随着社会和经济的不断发展,为适应人口及资源流通的需求,列车的运行速度和牵引重量在不断提高,我们除了要加大牵引力外还务必要提高机车、车辆的制动性能。支撑着所有铁道车辆安全运行的基本要素就是制动装置,“安全制动停车”是铁道车辆必须具备的功能。制动装置的性能不仅是保障行车安全的必要手段,同时也是提高列车速度和铁路通过能力的重要因素。本文主要做的是列车制动解算部分的研究,制动解算是列车牵引计算的一部分,所以在充分掌握了牵引计算理论的基础上,对列车制动过程中的不同情况进行数据计算和公式推导,在对列车的紧急制动距离和制动限速进行计算时,本课题选用功能强大的Matlab进行的程序设计及计算。通过Matlab的GUI建模功能,构建解算系统。然后对系统进行反复计算测试,并对计算结果进行分析,确保编辑的系统运行稳定,计算结果准确。为此,我将围绕课题查询、收集相关资料,推导机车制动力、制动距离、换算制动率等的理论公式,构建出模型,最终完成Matlab的程序设计,达到课题预期目的。80890

Research and Design of Train Braking Problem Solving System
Abstract:With the continuous development of society and economy, in order to meet the needs of population and resource circulation, train running speed and traction weight is increasing, we must increase the traction, but also must improve the locomotive, vehicle braking performance。 The basic element that supports the safe operation of all railway vehicles is the brake, "safe brake parking" is the railway vehicle must have the function。 The performance of the brake is not only a necessary means of guaranteeing traffic safety, but also an important factor in improving the speed of the train and the capacity of the railway。This paper mainly deals with the research of train brake calculation part。 Braking solution is part of traction calculation。 Therefore, based on the theory of traction calculation, the data calculation and formula of train braking process are carried out。 In this paper, we use the powerful Matlab to design and calculate the emergency braking distance and braking speed limit of the train。 Through the GUI modeling function of Matlab, the solution system is constructed。 And then the system to calculate the test again, and the results of the analysis to ensure that the editing system is stable, the results are accurate。 To this end, I will focus on the subject query, collect relevant information, derive the motorcycle braking force, braking distance, conversion braking rate and other theoretical formula to build the model, the final completion of Matlab programming to achieve the desired purpose of the project。
