- The conventional Wheel assembly is optimized using Stub and Hub integration by researching and evaluating new assembly designs, Material selection using Charpy impact test on different materials (EN24, 20MNR5, EN36) with different hardening processes (through hardening, Carburizing) are evaluated for the best combination of material and type of hardening which absorbs highest impact energy, which further evaluated for different types of brittle and ductile failure on those specimens, Component designing is performed considering various boundary condition evaluated for BAJA SAE ATV which includes Bump force due to hill fall down, Tension/Compression generation in case of improper landing on wheels, Torsion transfer through axle and Lateral forces due to centrifugal forces were used for design calculation and then FEA is used for Design validation. Finite model is generated in Hypermesh using various Meshing techniques considering rotating symmetry for achieving good quality criteria. Hub and knuckle of the wheel assembly is Optimized using Topology optimization to generate a material-efficient model as per stress flow in the structure. All these techniques resulted in a significant weight drop of 35 % percent compared to the last Conventional wheel assembly.
