Аннотация

The article presents a numerical simulation of the spatial distribution of temperature fields in the spring elements of freight wagons of railway transport during heat treatment. The use of modern CAE systems such as ANSYS has made it possible to analyze thermal processes in real time, which ensures precise control of technological parameters. The simulation aims to optimize heating and cooling modes, minimize internal stresses and deformations, and identify areas of potential defects. The paper considers the parameters of a spring made of 60Si2CrVA grade steel, performs a transient thermal analysis, and determines the optimal conditions for achieving the required mechanical properties. The simulation results show that it takes about 900 seconds to reach a quenching temperature of 880 °C with a rod diameter of 30 mm, while the temperature difference between the surface and the core of the product is 1.25 °C, which indicates minimal internal stresses.
