Study Analysis of Car Rim Design and Mechanical Properties Using Catia

This study discusses the design of a car rim and analyzed its mechanical properties using three different basic materials: aluminum, steel, titanium. The purpose of this study is to reduce production time and to minimize the risk of design failure. In this study using the Catia software to design a rim, then simulate the effect of applying force on a component, applying a certain working pressure, then able to perform calculations and display the results for analysis. The analytical method used is the FEM method of static analysis. The mesh type uses a linear tetrahedron mesh. Provision of clamps or fixed constraints is carried out on the surface of the bolt hole, where this surface is in contact with the wheel holder of car drive system. Then given a circumferential loading of 200 kN/m2. It was found that aluminum material is the best for the manufacture of car rims, which has a low density so it is lighter than steel and titanium. However, alloys such as lead and magnesium are needed to increase their hardness, and chromium alloys are needed to protect the rims from corrosion due to use in a polluted environment and contain impurities that can trigger corrosion.

Aftermarket Wheels Numerical Simulation To Get Maximum Stress and Deformation Values

The purpose of this research is to get wheels with offset variants of -15, +20, and +35 made of aluminum alloy with a maximum load of 690 kg. Autocad 2018 and Unigraphic NX 8 were used to create all three designs. The load was calculated using the SAE J2530 standard and simulated using the ANSYS Workbench 14.5 application's numerical simulation method. As a result, the car rim is designed with a spoke form that becomes steeper (Concave) as the offset decreases. Methods a) Dynamic Cornering Fatigue Test, b) Dynamic Radial Fatigue Test, and c) Impact test consecutively at offset -15 of a) 62.33 MPa, b) 111.61 MPa, and c) 1.58 mm can be used to obtain numerical simulation results. For offsets of +20 of 70.91 MPa, 75.75 MPa, and 1.6 mm. And a) 90.33 MPa, b) 78.13 MPa, c) 1.61 mm at offset +35.

Dynamic Design and Analysis of Car Wheel Rim Using FEA Method

Abstract: The wheel rim is one of the most critical components of the vehicle. Therefore, a number tests have to be performed on it do that, it could meet the safety requirement . But physical testing of wheel rim during their devolvement is very costly and time consuming. So finite element analysis has developed as a major tool for analysis purpose. The wheel rim is designed by utilizing SOLIDEDGE software. 3-D model of wheel rim as a IGES file is imported to ANSYS for investigation work. A solver mode in ANSYS programming computes the stresses, deformation, shear stress. Here Car rim with concrete road model has made on Solid rim and simulate by ANSYS software. Through dynamic analysis find out three parameters results like deformation , Stress and Shaer stress.In this study car wheel is running 100 km/hr speed with fully loaded car.then find out variou results and compare results with exiting materials ( Steel material).Find out deformation values for Magnesium Alloy , Aluminium Alloy and Steel S-7 results are respectively like 7.99mm , 8.218 mm, 8.56 mm. here cleared seen that Magnesium Alloy has less deformation value compared to other then material deformation value so it is good for future design consideration. Find out stress values for Magnesium Alloy, Aluminium Alloy and Steel S-7 results are respectively like 102.52 MPa , 153.08 Mpa and 390.9 MPa. here cleared seen that Magnesium Alloy has less deformation value compared to other then material stress value so it is good for future design consideration. Find out shear stress values for Magnesium Alloy, Aluminium Alloy and Steel S-7 results are respectively like 59.12 MPa , 88.378 Mpa and 212.77 MPa. here cleared seen that Magnesium Alloy has less deformation value compared to other then material shear stress value so it is good for future design consideration.

Energy harvester for rotating environments using offset pendulum and nonlinear dynamics

We present an energy harvester for environments that rotate through the Earth’s gravitational field. Example applications include shafts connected to motors, axles, propellers, fans, and wheels or tires. Our approach uses the unique dynamics of an offset pendulum along with a nonlinear bistable restoring spring to improve the operational bandwidth of the system. Depending on the speed of the rotating environment, the system can act as a bistable oscillator, monostable stiffening oscillator, or linear oscillator. We apply our approach to a tire pressure monitoring system mounted on a car rim. Simulation and experimental test results show that the prototype generator is capable of directly powering an RF transmission every 60 s or less over a speed range of 10 to 155 kph.

Optimization of Car Rim Using OptiStruct

Automobile industries requiere manufacturing vehicules at optimum coste and with greater safety. For this purpose every component of vehicle is analysed for critical conditions. In this work car rim is considered for optimization by using finite element method. The optimization is carried to minimize the weight of rim without exceeding allowable strain. The intention is to create the geometry utilizing parameters for all the variables, deciding which variables to use as design, state and objective variables to obtain an accurately converged solution. FEM software OptiStruct is used for optimization of rim. If the stress & strain values are within the permissible range, then certain dimensions are modified to reduce the amount of material needed. The procedure is repeated until design changes satisfy all the criteria. For experimental verification similar type of object is used and stresses in it are calculated for set load with suitable instrumentation. Then same is calculated in OptiStruct software and Experimental results are compared with FEM results. Keywords: Impact factor, Strain gauge, Vonmises stress,Optistruct, Strain indicator.

On optimization of a car rim using finite element method

This paper presents the optimization of an octopus-type car rim for which critical zones were found first and then optimum thickness was investigated using an elasto-plastic analysis. In this study, three-dimensional finite element method was used for conducting elasto-plastic analysis. In the finite elements analysis, the elements forming the meshes are hexahedral linear elements with eight nodes. Twelve different meshes were used. A quadrant of the rim was utilized due to its symmetric shape. The theoretical results were compared with experimental ones. It seems that the theoretical results are in agreement with the experimental ones. The results are presented in tabular and graphical forms.
