Software Application for Determination of Brake Efficiency of Freight Trains According to the Rules of Gost 34434-2018

Abstract

Calculation algorithm for braking distances of a freight train and recalculation on cast iron brake shoes in accordance with new rules of GOST 34434-2018 "BRAKE SYSTEMS OF FREIGHT CARS. Technical requirements and calculation rules " is given. According to the above mentioned algorithms, a program was drawn up in the Excel environment, intended to complete automation of the process of computational research to determine the braking efficiency of a freight train. The program is universal, as it allows studying brake systems of different design: with one and two brake cylinders; with one-sided and two-sided application of brake shoes on wheels; with disc brake. Examples of calculation studies of the braking efficiency of the open-top car with an axial load of 25 tons are shown.
