| Popis: | The aim of this work was to investigate the stress analysis of crankpin fillets of a crankshaft. Fatigue failure in the crankpin fillet zone is one of the primary causes of the breakdown of crankshafts. In this paper, a polarization–optical method (photoelasticity) was used to study the distribution of stresses from bending in the crank-throw plane of a crankshaft on flat transparent photoelastic models. Results showed that the influence of the radius of crankpin fillet on the value of the stress concentration coefficient is estimated. Results achieved can be used in fatigue life calculation and optimization of this component. |
