automotive wheel rim using Ansys software .we have design this wheel rim using Catia and imported into ansys software for further analysis. In this work we are going to carry out the radial load fatigue test on newly designed rim with material and design optimization. Also validate the results experimental results.
2. PROBLEM STATEMENT The failure of rim wheel is due to crack initiated near the hole which further gets propagated throughout the rim which leads to fatigue failure. In order to improve the Fatigue life of rim, material optimization and design optimization is necessary for which best material has to be selected by conducting design of experiments to find parametric design which gives higher fatigue life.
Key Words: Wheel rim, Design, Analysis, Optimization
1.INTRODUCTION A wheel rim is a highly stressed component in an automobile that is subjected to bending and torsional loads. Because of the long life and high stresses, as well as the need for weight reduction, material and manufacturing process selection is important in rim design. There are competitions among materials and manufacturing processes, due to cost performance, and weight. This is a direct result of industry demand for components that are lighter, to increase efficiency, and cheaper to produce, while at the same time maintaining fatigue strength and other functional requirements.
3. OBJECTIVE 1. To design the proposed automotive wheel rim. 2. To carry out stress and fatigue analysis of wheel by using finite element method. 3. To study the effect of various materials on fatigue life of the rim. 4. To optimize thickness of rim to reduce the material consumption and improve life of component by using advanced fatigue strain life approach. 5. To develop the experimental setup for proposed automotive wheel rim. 6. To compare experimental and finite element analysis results.
In the fatigue life evaluation of aluminum wheel design, the commonly accepted procedure for passenger car wheel manufacturing is to pass two durability tests, namely the radial fatigue test and cornering fatigue test .Since alloy wheels are designed for variation in style and have more complex shapes than regular steel wheels, it is difficult to assess fatigue life by using analytical methods. The newly designed wheel is tested in laboratory for its life through an accelerated fatigue test. Based on these test results the wheel design is further modified for high strength and less weight. But stress analysis will not yield the optimum wheel design described a probability based model for prediction of fatigue failure of automotive wheel rim. Aluminum alloys, magnesium alloys and structural steel are the three important materials by which rim of wheel is casted and then manufactured. Fatigue life of all of these three components gets varied. It is necessary to know the fatigue life of each of these materials. By conducting design of experiments best parametric design can be done. Also thickness of the rim can be varied for each of these materials. It is stated that by varying the thickness level we can get varied fatigue strength for different materials. It is

4. Methodology: In this dissertation work it is proposed to study the effect of various materials on fatigue life of the automotive wheel rim by using finite element analysis and radial load testing. Phase I – Literature Survey. In this phase literature survey of fatigue life analysis, Design optimization etc. will be carried. Phase II – One of the method to find fatigue life of rim is by conducting radial load test. This Phase includes fatigue analysis of newly designed rim by finite element analysis and by radial Load test. A) Experimental work: We are going to carry out fatigue life analysis of rim by radial load technique as follows.
