Abstract – The purpose of the 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 study a tire of car wheel rim
belonging to the disc wheel category is considered. Design in an important industrial activity which influences the quality
of the product. The wheel rim is designed by using modelling software Solid Work 2015. In modelling the time spent in
producing the complex 3-D models and the risk involved in design and manufacturing process can be easily minimised. So
the modelling of the wheel rim is made by using Solid Work 2015.
Solid Work Simulation is the latest used for simulating the different forces, pressure acting on the component and
also for calculating and viewing the results. A solver mode in Solid Work Simulation calculates the stresses, deflections,
bending moments and their relations without manual interventions, reduces the time compared with the method of
mathematical calculations by a human. Solid Work Simulation static analysis work is carried out by considered two
different materials namely aluminium and forged steel and their relative performances have been observed respectively. In
addition to this rim is subjected to vibration analysis (modal analysis), a part of dynamic analysis is carried out its
performance is observed.

III. BASIC STEPS OF FEA ANALYSIS FOR 1080 MILD STEEL
(1) Preprocessing: defining the problem
The major steps in preprocessing are define key points/lines/areas/volumes,
(i) define element type and material/geometric properties,
(ii) Mesh lines/areas/ volumes as required. The amount of detail required will depend on the
dimensionality of the analysis, i.e., 1D, 2D, ax symmetric, and 3D.
(2) Solution: assigning loads, constraints, and solving
Here, it is necessary to specify the loads (point or pressure), constraints (translational and rotational), and
finally solve the resulting set of equations.
(3) Post processing: further processing and viewing of the results
In this stage one may wish to see lists of nodal displacements,
(i) element forces and moments,
(ii) deflection plots, and
(iii) Stress contour diagrams or temperature maps.
