Multivariate verification method for calculating standards for anchoring of rolling stock on railway station tracks
In the article, the authors present the development of a method for calculating the norms of fixing rolling stock, which allows reducing the impact of negative factors and solving the problem of the lack of options for calculating the fixing of the trains consisting of heterogeneous rolling stock in particular cases of longitudinal profiles of the station tracks. The method allows you to calculate the fixing standards based on the forces acting on the rolling stock, reduce the required number of the brake shoes required for fixing the rolling stock, and calculate the number of the brake shoes, depending on the choice of options for lying under certain cars. A comparison of the norms of fixing defined on the basis of the current and proposed methods for consideration is made. It also offers a solution to the problem of the lack of clear rules for fixing rolling stock consisting of different lengths cars. The directions of increasing the reliability and efficiency of securing trains and free-standing cars on station tracks with minimizing the human factor and regulating the calculation of fixing standards are formulated. On a concrete example, the anchorage norms for a train consisting of physically dissimilar cars on a monotonous profile of the receiving and sending route are determined.
