The velg on the car is a frame of a wheel that withstands the forces and stresses caused by the weight of the vehicle and the blow from the track surface The blow from the surface of the track cun comeve stress and deformation of the velg Aluminum alloy velg have areax called critical zones located in the hub, spoke, and flange areas. One of the strength of the velg in receiving stress is influenced by the shape of the spoke. The purpose of this study is to compare several models of wheels that have been modified in order to find the maximum design. The velg that were analyzed consisted of model i velg with a spoke radius of 4 mm, model 2 velg with a spoke radius of 8 mm and model 3 velg with a spoke radius of 12 mon. The research was conducted in several stages, starting with literature studies from journals and previous research related to dynamic cornering fatigue testing. The research includes the standards used, simulation modeling, and loading. This test refers to the Society of Automotive Engineer (SAE) J 328 standard. The velg are modeled using Autodesk Inventor software and simulated using ANSYS Workbench software. After the simulation, the value of equivalent von misses stress, equivalent elastic strain and fatigue life of the three wheel models is obtained, the first velg design model 1 has an equivalent von misses stress value of 75,022 MPa, equivalent elastic strain strain of 0,0016627 mm/mm and the value of fatigue life is 1,000.000 cycle, for model 2 velg it has an equivalent von misses stress value of 119,53 MPa. equivalent elastic strain of 0.001862 mm/mm and a fatigue life value of 1,000.000 cycle, and finally the velg simulation model 3 obtained the equivalent von misses strest value of 136,96 MPa, the equivalent elastic strain strain of 0,0019852 mm/mm and the fatigue life value of 841.040 cycle. With the SAE J 328 standard set which is 500,000 cycle. From all wheel models, seen from the simulation results, it is stated that they meet the SAE J 328 standard, but from the data on equivalent von misses stress, equivalent elastic strain and fatigue life, it can be stated that the wheel design model i is better than the wheel design model 2 and 3 because the wheel design is model I has a large fatigue life value and an equivalent von misses stress value, the equivalent elastic strain has a smaller value.
