The article presents study results of the influence of crankshaft construction changes on the choice of support conditions allowing to eliminate deflections and elastic deformations of crankshafts under their self-weight. For the purpose of this study we implemented a programme for strength calculations Nastran FX 2010 which enables modelling the research subject with a finite element method and counting the value if reaction forces ensuring zero value of deflections on main journals at a change in the crankshaft’s angle of rotation.
