Problems solved by technology

However, due to the increase of the mass of the train and the increase of the length of the train, the traction force and braking force during operation will increase, and the transmission time of the braking wave will also be lengthened
[0003] In order to strengthen the analysis and research on the air braking system of freight trains (especially long-formed freight trains), and correctly analyze the braking performance and braking characteristics of long-formed and heavy-duty freight trains, developed countries such as the United Kingdom and the United States have successively emerged Various simulation devices and simulation methods for the air brake system of fixed marshalling freight trains, but because many key parameters of the train air pipeline cannot be directly obtained, resulting in a disconnection between theory and reality, from theoretical calculation data and real vehicle tests It can be seen from the comparison of the data that the existing simulation devices and their simulation methods are often unable to take into account various types of train models, Calculation of air pressure in various vehicle configurations
