The vehicle may be towed without the engine but it is not possible without the wheels. Road wheel is a significant structural member of the vehicular suspension system that supports the static and dynamic loads encountered during vehicle operation. As in the case of an automobile wheel maximum load is applied on the alloy wheel. Proper analysis of the alloy wheel plays a significant role for the safety of the passenger cars. Alloy wheels which are intended for normal use on passenger cars, undergo three tests and have to pass before going into the production: Dynamic Cornering Fatigue Test, Dynamic Radial Fatigue Test and Impact Test. Most of aluminium alloy wheels manufacturing companies have done several testing of their product however information of their method on simulation test is often kept limited. During a part of research a static and fatigue analysis of aluminum alloy wheel A356.0 was carried out using FEA package. The 3-D model was imported from CATIA into ANSYS using the appropriate format. Finite element analysis (FEA) is carried out by simulating the test conditions to analyze stress distribution and fatigue life of the aluminium alloy wheel rim of passenger car. Experimental analyses are carried out by radial fatigue testing machine for evaluation of fatigue life under influence of camber angle. The test indicates that integrating FEA and nominal stress method is a good and efficient method to predict alloy wheels fatigue life. In this paper by observing the results of both static and dynamic analysis the aluminium alloy is suggested as better material.

Analysis of Static Stress in an Alloy Wheel of the Passengercar

Importance of wheel in the automobile is obvious. The vehicle may be towed without the engine but at the same time even that is also not possible without the wheels, the wheels along the tire has to carry the vehicle load, provide cushioning effect and cope with the steering control. Generally wheel spokes are the supports consisting of a radial member of a wheel joining the hub to the rim. The most commonly used materials for making Wheel spokes are with features of excellent lightness, thermal conductivity, corrosion resistance, characteristics of casting, low temperature, high damping property, machine processing and recycling, etc. This metal main advantage is reduced weight, high accuracy and design choices of the wheel. This metal is useful for energy conservation because it is possible to re-cycle. Spokes make vehicles look great but at the same time they require attention in maintenance. To perform their functions best, the spokes must be kept under the right amount of tension. The two main types of motorcycle rims are solid wheels, in which case the rim and spokes are all cast as one unit and the other spoke wheels, where the motorcycle rims are laced with spokes. These types of wheels require unusually high spoke tension, since the load is carried by fewer spokes. If a spoke does break, the wheel generally becomes instantly unridable also the hub may break. Presently, for motor-cycles Aluminium alloy wheels are used, currently now replacing by new magnesium alloy due its better properties than Al-alloy. An important implication of this paper or the problem stated here is to "analyse the stress and the displacement distribution comparing the results obtained". In addition, this work extends Proper analysis of the wheel plays an important role for the safety of the rider. This paper deals with the static &fatigue analysis of the wheel. The present work attempts to analyse the safe load of the alloy wheel, which will indicate the safe drive is possible.

Structural and Fatigue Analysis of Two Wheeler Lighter Weight Alloy Wheel

Wheels are the main components of the car. The wheels with tires provide the better cushioning effect to the car. Without engine a car may be towed but at the same time a car cannot be towed without wheels. . The main requirement of the vehicle or automobile tires are it must be perfect to perform its all the functions. Reverse engineering is a good method to redesign the old component. The wheels have to pass different tests for best performance like static analysis, vibration analysis etc. In this project a wheel was considered for the analysis. During the part of the thesis project aluminium alloy was carried out for the FEA analysis. Design is an important manufacturing activity which provides the quality of the product. The 3-dimensional model of the alloy wheel was designed by using the technology reverse engineering. The 3-dimensional model was designed in the modelling software CATIA v5.and further it was imported to the ANSYS 15.0 by using IGES format. The finite element analysis of the model was meshed by using 10 node tetrahedron solid element. The static condition was chosen for the analysis. This was constrained in all degree of freedom at the bolt. The pressure was applied on the outer rim surface of the alloy wheel. In the analysis, the results of the equivalent stress, safety factor, and deformation were calculated. In this analysis the von-misses stress were below the yield strength. All the results which were analyzed are good for the design which was drawn by reverse engineering.

Lightweight of automatic vehicle is a significant application trend, using topology optimization and magnesium alloy materials is a valuable way. This article designs a new model of automobile wheel and optimizes the structure for lightweight. Through measuring and analyzing designed model under static force, clear and useful topology optimization results were obtained. Comparing wheel performance before and after optimization, the optimized wheel structure compliance with conditions such as strength can be obtained. Considering three different materials namely magnesium alloy, aluminum alloy and steel, the stress and strain performances of each materials can be obtained by finite element analysis. The reasonable and superior magnesium alloy wheels for lightweight design were obtained. This research predicts the reliability of the optimization design, some valuable references are provided for the development of magnesium alloy wheel.

Multi-objective Optimization Design of Magnesium Alloy Wheel Based on Topology Optimization

The essence of car wheel rim provides a firm base on which to fit the tire. Its dimensions, shape should be suitable to adequately accommodate the particular tire required for the vehicle. In this paper a tire of car wheel rim belonging to the disc wheel category is considered. Design is an important industrial activity which influences the quality of the product. The wheel rim is modeled by using AutoCAD software. Later this AutoCAD model is imported to ANSYS for analysis work. ANSYS is the latest software used for simulating the different forces, 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 static analysis work is carried out by considered two different materials namely aluminium alloy and Magnesium alloy and their relative performances have been observed respectively. In addition to wheel rim is subjected to model analysis, a part of dynamic analysis is carried out its performance is observed. In This paper by observing the results of static analysis obtained Magnesium steel is suggested as best material.
