Abstract: The rim of the wheel, which is its outermost portion, supports the tyre and is a key element in maintaining its round shape. This paper discusses how to design wheel rims and how to evaluate them while considering things like cracking, bending, impact loads, vibration, tyre hold pressure, rust, dents, other structural failures. Increased vibration, reduced air pressure, and even structural failure can result from these harms. In this paper the natural frequencies were obtained by the modal analysis in Ansys for the structural steel and the aluminium alloy materials to validate the natural frequencies along with the total deformation obtained using the FEM tool. With the use of Ansys, natural frequencies with various mode shapes may be designed, analysed, and calculated, making it simple to identify the components that are most susceptible to resonance and deformation. A wheel rim's natural operating frequency is 150.98 Hz, which does not coincide with the natural frequencies and suggests that there is no inclination towards resonance. For the materials structural steel and aluminium alloy, the ten mode forms of natural frequencies were documented in the form of a table. The wheel rim avoids the crucial resonance because the working or operational frequency is different from the natural frequency.
