| Abstract: | Stress concentrations which lie in interference fit joints effect directly on the reliability of the joints and their fatigue life, so all the effective factors during design and manufacturing must be considered. Three-dimension FE simulation of locomotive wheel and shaft can simulate the stress distribution with exactl reflection of stress concentrations. In addition, the plastic deformation of the locomotive wheel and shaft is discussed. The design and the check of interference fit joints with FEA are more practical and reasonable. |
| Keywords: | wheel and shaft stress concentration finite element elasticity and plasticity |
