Hypothesis
The master S-N curve method provides a more reliable evaluation of fatigue damage in high-ply cutter bodies compared to traditional methods.
Conclusion
The master S-N curve method is effective in evaluating the fatigue damage of high-ply cutter bodies, with all calculated damages below the safety threshold.
Supporting Evidence
- The maximum fatigue damage calculated by the master S-N curve method is 0.223, which is the safest.
- Fatigue damage of the three measuring points calculated by the three methods is all below 0.5.
- The master S-N curve method provides an efficient and high-precision approach for the anti-fatigue design of cutter bodies.
Takeaway
This study shows how to check if a cutter is strong enough to last a long time without breaking, using a special method to measure its strength.
Methodology
Finite element simulation was used to analyze the cutter body, and fatigue damage was assessed using the master S-N curve method and traditional methods.
Limitations
The study primarily focuses on three key welds and may not account for all potential failure points in the cutter body.
