This article is devoted to solving urgent problems related to the development of a mathematical model and methods for assessing the dynamic characteristics of railway wheelsets. In the simulation, railroad wheelsets are considered as a one-dimensional deformable body based on the Bernoulli-Euler theory with two rigid disks. The cross-section of the shaft is assumed flat and perpendicular to the centerline during vibration. Disks are modeled as a rigid body characterized by mass and moment of...
