摘要

本文对现代 STADLER KISS 列车的牵引传动装置进行了研究。文章讨论了牵引传动装置的技术水平对列车制动特性的影响。提出了创新型牵引减速器的应用方案,该方案可根据牵引传动装置的单位消耗量提高效果指标。将减少拟议的推力减速器的质量作为影响制动系统的主要因素之一,说明了减少旋转部件惯性系数和列车运动方程中考虑的技术参数的可能性。考虑到制动距离的计算方法,在一个实际例子中计算了不同速度范围内的制动距离,通过评估制动效率,显示了将制动距离减少 5%并按比例减少制动时间的可能性。研究人员的实验结果表明,由多级创新减速器组成的牵引传动装置的技术水平直接影响列车的运行。因此,提高转动部件的惯性系数值应能加快列车的加速和制动时间,快速通过平地,减少制动距离并节省一些燃料资源。通过进行紧急制动试验,确定了列车制动距离和制动时间的实验值,并确认其与报告值一致。考虑到拟议减速器的优点,对制动距离和制动时间与速度的关系图进行了比较说明

Study of the influence of the technical level of railway vehicles on braking characteristics
In the article, the traction transmission of modern STADLER KISS trains is studied. The study of the effect of the technical level of the traction transmission on the braking characteristics of the train is discussed. The application of an innovative traction reducer is proposed, which allows to increase the result indicator according to the unit consumption of the traction transmission. Taking the reduction of the mass of the proposed thrust reducer as one of the main factors shaping the effect on the braking system, the possibility of reducing the inertia coefficient of the rotating parts and the technical parameters considered in the equation of motion of the train is shown. Taking into account the method of calculating the braking distance, the braking distance in different speed ranges is calculated in a practical example, by evaluating the braking efficiency, the possibility of reducing the braking distance by 5 % and reducing the braking time in proportion is shown. As a result of the experiments carried out by the researchers, it became clear that the technical level of traction transmission, consisting of multi-stage innovative reducers, directly affects the movement of trains. Thus, increasing the value of the coefficient of inertia of the rotating parts should allow accelerating the acceleration and braking times of the trains, passing the flats quickly, reducing the braking distance and saving some fuel resources. By conducting emergency braking tests, experimental values of the train's braking distance and braking time were determined and their compliance with the reported values was confirmed. Taking into account the advantages of the proposed reducer, a comparative description of the graphs of the dependence of braking distance and braking time on speed is given
