Modal analysis is a method used to study the specific vibration characteristics of an object under natural modes. For wheel hubs, modal analysis effectively identifies their vibration characteristics under different limitations, thereby further optimizing the design. This paper establishes a wheel hub model using UG software and performs a modal analysis of a circular aluminum alloy wheel hub using ANSYS. The calculated results of the first ten modal frequencies demonstrate that the overall structure of the wheel hub is relatively safe. This study provides a valuable reference for the simulation analysis of similar types of wheel hubs.
