Abstract
Currently widely used methods for determining the stopping distance of railway rolling stock have a number of drawbacks that affect the accuracy of the calculation results. The aim of the study is to develop a calculation method that allows to take into account the main parameters of the process of unsteady braking (the speed of propagation of the brake wave; feature of the brake cylinder filling diagram; brake mode; the initial speed at which the calculation of the actual stopping distance begins). The methods used in the work allowed us to obtain equations for calculating the specified parameters of the nonstationary mode of the brakes. The results of computer simulation of the stopping distance of the train are presented and the analysis of the parameters obtained using various methods for calculating the stopping distance is carried out. The values of the stopping distance of the train, preparation of brakes and the actual stopping distance are determined. Comparison of the calculation results for the proposed method was performed using computer simulation and the method of integrating the equation of motion over the speed intervals. The proposed method allows more accurate calculations of the stopping distance of railway rolling stock.
