Method & Evidence

AimTo investigate the effectiveness of topology optimization and transient analysis using FEM to reduce the weight of a knuckle joint while ensuring its reliability under dynamic loading conditions.

MethodSimulation and Optimization

ProcedureA knuckle joint model was created in SolidWorks and then imported into ANSYS Workbench. Topology optimization was performed to identify areas of low stress and material that could be removed. Transient analysis was conducted to simulate the dynamic response of the optimized joint under specific loading conditions. Different levels of weight reduction (20%, 35%, 50%) were targeted.
