TESI IN AZIENDA E TIROCINIO: ROTATING FATIGUE (BENDING) IN TRANSMISSION SHAFTS AND SPLINES
Tesi esterna in azienda
Riferimenti CRISTIANA DELPRETE, CHIARA GASTALDI
Gruppi di ricerca 20- ISED: Industrial Systems Engineering and Design
Descrizione The thesis+internship experience is composed of two main activities
1. LITERATURE REVIEW AND SELECTION OF FATIGUE ALGORITHM IN FESAFE
Need to check that current FeSafe setup is able to properly capture the physics of rotating and torsional fatigue in shafts.
Study on a simplified system: shaft with one gear, torsion, spline and bending stress (multiaxial). Analysis in fatigue using literature approaches (Gough and Pollard, DIN, etc…). Multiaxial fatigue. Infinite life. Simplified load case could be considered as starting point.
2. INVESTIGATION ABOUT FESAFE ALGORITHM:
Analysis is repeated using Abaqus (FEA) and FeSafe. Different algorithms in FeSafe are used. The one providing closest results to literature is selected to go ahead with the activity.
NOTE: if possible, the simplified load case can be replaced by some blocks and comparison can be presented between literature and FeSafe approach.
NOTE: PLANNED START OF THE ACTIVITY: FROM JANUARY 2025 AND AHEAD
