Abstract. In this article, the causes of possible failures in the welds and near-weld structures of locomotives (main frame, bogie frame and body) and their elimination methods are considered. Analysis of welded joints and their optimization possibilities were studied using the Finite Element Method (FEM).

Keywords: finite element method (FEM), load-bearing structures, locomotive frame, bogie frame, SolidWorks Simulation, weld, fatigue cracks, cyclic loading.
