Knuckle Joint | Structural and Fatigue Assessment

Completed educational ANSYS Mechanical study of a knuckle joint assembly under torque. The goal was to understand load transfer, locate critical stress regions, and assess fatigue under fully reversed loading. The workflow covered component selections, steel material properties, bonded-contact assumptions, supports, quadratic solid meshes, and static structural analysis. A mesh sensitivity study and reaction-torque balance check supported the interpretation. Assembly and component contours were used to explain deformation, equivalent stress, fatigue life, and fatigue safety factor. Solver contact warnings were addressed by revising the bonded-contact formulation. The assessment identified fatigue-critical regions and documented why the assumed assembly did not meet the target fatigue criterion. Deliverables included a solved model, an illustrated report, and genuine result plots. MENO SIM - Model. Solve. Verify. This is an educational case study using a simplified bonded-contact, linear-elastic model and a generic steel fatigue curve. It does not establish experimentally validated performance or design certification.
