Abstract: The mechanical stresses arising at natural and forced vibrations of the frame of traction engine NB-514 of alternating current electric locomotives in the area of the emerging crack between the inspection and ventilation windows of the frame of traction engine NB-514 are considered by the finite element method. It is shown that the maximum mechanical stresses occur in the corners of the windows and can be almost 2 times reduced by correcting the shape of the windows. The grid convergence of calculations is considered, which does not strongly affect the calculations on reduction of mechanical stresses at window shape correction. The obtained data show the possibility of structural optimization with the help of high-quality models - digital twins.
