Abstract The paper presents the key aspects of using digital technologies in mechanical engineering covering the stages of design and technological preparation of production. The methodology for creating 3D CAD models, forming design and technological documentation, creating virtual assemblies and digital twins using 1D and 3D modeling are described. Examples of numerical tests and practical implementation of developments are given on the example of diesel engine components and assemblies for transport systems.
Keywords digital technologies, decomposition, digital twins, heat and mass transfer, numerical simulation, verified and validated physical and mathematical model, aerodynamics, strength
