Description
Summary:The strength and reliability of the additively manufactured titanium alloy wheel hub have been investigated and analyzed. The running speed of the supercar, which utilizes the additively manufactured titanium alloy wheel hub, is divided into three levels. The impact power on the wheel hub is computed for each speed level. Then, the maximum stress of the wheel hub under each level of impact is obtained using finite element analysis. Formulas for calculating the residual strength and reliability under each level of fatigue impact are provided. Additionally, formulas for calculating residual strength and reliability of wheel hubs, considering the random cross occurrence of the three types of impacts, are given. Finally, the changes in residual strength and reliability are analyzed. This method is not only suitable for the reliability calculation of additively manufactured titanium alloy wheels but also applicable to the reliability calculation of other alloy wheels.
