Determining and analysing support conditions at variable construction of crankshafts

Nozdrzykowski K., Grządziel Z., Harušinec J.

New Trends in Production Engineering

2018

Vol. 1, Iss. 1

553--560

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.
