Determine cyclic stress distribution in a gear tooth under torque. Geometry: • Module: 4 mm, 20 teeth, pressure angle: 20°. • Tooth profile: Standard involute. Material: Alloy Steel (E = 210 GPa, ν = 0.3, S-N curve data). Boundary Conditions: • 100 Nm torque applied to gear hub. • Cyclic loading (R = 0, frequency = 10 Hz). Analysis Steps (Simulia/Abaqus): 1. Static structural analysis for stress. 2. Fatigue analysis using Goodman correction. 3. Define contact pairs between meshing teeth. Parameters to Vary: Torque magnitude (100 Nm vs. 150 Nm). Deliverables: • Stress distribution on tooth flank. • Fatigue life contour plots. • Critical crack initiation zones. Validation: Compare with AGMA gear stress equations.
