Design and Analysis of Rear Wheel Upright Using 3D Printing Technology

Deepanshu Mittal

The Rear Upright is the most important part of the rear wheels which is connected to the suspension system and rear wheel hub of a vehicle. It gives a rotating motion to the rear hub using taper bearing fitted inside it to bear radial as well as axial loads in dynamic conditions. The main aim of the Automotive Industry is to increase the overall efficiency and decrease the manufacturing cost. In this paper I have designed the Rear Wheel Upright of an All-Terrain vehicle for two different manufacturing methods using Autodesk Fusion 360 and Solid works 2019 and further done the static structural analysis using ANSYS Workbench 18.1 by constraining the upper arms of the rear upright and applying remote force on the spindle point from contact patch of the tire combining all the lateral and longitudinal forces acting on Upright. Final aim is to show that additive manufacturing is better method than subtractive type manufacturing as it increases the component performance. In this, first I designed for subtractive manufacturing i.e., CNC manufacturing using AL6061 and optimized it by designing lightweight component with needed Factor of Safety which is fabricated by additive manufacturing i.e., 3D Printing using same material. Final output is obtained by applying calculated forces and using Finite Element Analysis (FEA).
