The paper contains main structural disadvantages of 18-100 bogies, namely large unsprung mass, instability of characteristics, low critical velocity, intense wear and others. The experience of domestic and foreign developments, devoted to improving the dynamics and energy efficiency indicators of freight wagon undercarriage, indicates the need for fundamentally new structures or deep modernization of existing bogies. To study the dynamics of freight wagon, the dynamic model in the licensed software complex “UM 6.0” was improved. As the first stage of verification of the model, a simple model of vertical vibration of a wagon with one degree of freedom was calculated. As the second stage of the verification of the computer model of the wagon dynamics, the data of measurements of accelerations of the elements of the wagon during the running dynamic tests performed in an empty and loaded state are used. According to the results of the simulation, the values of the dynamic coefficients of the spring-suspended and unsprung elements of the bogie are obtained. Technical solution and concept of new bogie are developed.
