OPTIMIZATION OF CAR RIM USING DESIGNING AND ANALYSIS SOFTWARES

The essence of the car wheel rim provides a firm base on which to fit the tire. Its dimensions, the shape should be suitable to adequately accommodate the particular tire required for the vehicle. In this project, a tire of the car wheel rim belonging to the disc wheel category is considered. The modern vehicle is also seen today as a fashion item to compliment people's individual requirements. Motor vehicles are produced according to very strict rules to ensure the safety of the passengers. Every component is therefore designed according to the criticality of the component. Wheels are classified as a safety-critical component and international codes and criteria are used or design as a wheel. The purpose of the car wheel rim provides a firm base on which to fit the tire. Its dimensions, the shape should be suitable to adequately accommodate the particular tire required for the vehicle. In this study, a tire of the car wheel rim belonging to the disc wheel category is considered. The wheel rim is modeled by using modeling software CATIA V5. By using this software the time spent in producing the complex 3- D models and the risk involved in the design and manufacturing process can be easily minimized. So the modeling of the wheel rim is made by using CATIA. Later this CATIA modal is imported to ANSYS for analysis work. ANSYS is the latest software used for simulating the different forces, the pressure acting on the component, and also calculating and viewing the results. By using ANSYS software reduces the time compared with the method of mathematical calculations by a human. ANSYS structural analysis work is carried out by considered two different materials namely aluminum forged steel and their relative performances have been observed respectively. The main objective of this paper is to conduct structural analysis on the car wheel rim for different materials with modified dimensions. In addition to this, the wheel rim is subjected to modal analysis, a part of dynamic analysis is carried out its performance is also analyzed
