Front Lower Control Arm (A-Arm Wishbone)

Refine the existing automotive front lower control arm A-arm model while preserving its two inner mounting points and one outer ball-joint mounting point. 1. Replace the thin rectangular connecting rods with broader, tapered structural arms having a realistic forged-aluminium-style geometry. 2. Create a smooth, continuous wishbone structure with rounded transitions between both arms and all three mounting bosses. 3. Add generous fillets of approximately 5–8 mm at arm-to-boss junctions. 4. Reinforce the mounting bosses with smooth, integrated material transitions or small gussets. 5. Preserve the three correctly positioned cylindrical through-holes and ensure they remain unobstructed. 6. Use an approximately 5 mm nominal arm thickness where a plate-like design is appropriate, with thicker mounting bosses and smooth transitions. Avoid unrealistic abrupt thickness changes. 7. Ensure the entire component is one watertight, solid CAD body without disconnected geometry. 8. Keep the geometry simple enough for finite element analysis in ANSYS Workbench. 9. Do not add bolts, rubber bushings, logos, decorative details, or separate components. 10. Preserve the overall dimensions and mounting-point positions unless a change is necessary for a coherent design. Export the refined model as STEP (.step or .stp) and retain the editable CAD model.
