- Summary:
- Automotive steel wheel rim is critical component for human safety. For validating steel wheel rim various tests will be performed at component and vehicle level. Cornering test performed at vehicle level is one of the tests, where wheel rim will be validated for high cornering loads. Cornering test performed at vehicle level consists of three different events clockwise(CW) rotations of vehicle, anti-clockwise(ACW) rotations of vehicle and figure of 8 rotations of vehicle. As wheel rim will experience different loading in each of the events of cornering test, correlating the virtual Finite Element Analysis (FEA) with physical test is quite challenging. If in FEA we are able to predict the damage and life very near to the physical validation, number of design iterations can be reduced. Also, it is possible to create a safe design of steel wheel rim for cornering loads. Vent hole shape and crown depth are two important aspects in wheel rim design. Vent hole shape and size will influence the heat dissipation of braking. Crown depth of disc will influence the stiffness of wheel rim design. The present study focuses on correlating the virtual FEA of wheel rim cornering test with physical validation and designing a steel wheel rim with desirable vent hole shape and required crown depth for cornering loads. For detailed study, wheel rim discs with four different crown depths and three different vent hole shapes are evaluated in FEA. Effect of crown depth and vent hole shape on fatigue life is captured from the analysis. Based on the study combination of required crown depth and vent hole shape is explored. This study helps in design of a wheel rim disc with required crown depth and vent hole shape to meet the cornering test durability life.Key Words: Wheel Rim, Disc, Vent Hole, Disc Crown
