The Fatigue Life of a Rotating Shaft project focuses on predicting and improving the shaft’s ability to withstand repeated cyclic stresses without failure. By analyzing stress concentration areas, surface finish, material properties, and loading conditions, engineers can extend the shaft’s operational life and prevent catastrophic breakdowns. This study helps identify safe operating limits and optimal design parameters for rotating machinery.

This project reduces the operational cost, eliminates fuel consumption, and is particularly useful in rural and off-grid locations where electricity supply is unreliable.

Parts Used:

1. Shaft Material – Commonly alloy steel, stainless steel, or carbon steel with defined mechanical properties.
2. Bearings – Support the shaft and maintain alignment.
3. Couplings – Connect the shaft to the driving or driven components.
4. Load Application System – Mechanism to simulate bending, torsional, or combined loads.
5. Surface Treatment – Coatings, case hardening, or shot peening for fatigue improvement.
6. Measurement Tools – Strain gauges, torque sensors, and tachometers.
7. Analysis Software – ANSYS, SolidWorks Simulation, or MATLAB for fatigue calculation and S-N curve analysis.
