The document summarizes a finite element analysis (FEA) conducted to optimize the design of a steering knuckle component for a 1200 kg sedan. The initial design was modeled and analyzed in ANSYS to evaluate stresses and deformation. The thickness of arms connecting to the steering shaft and suspension were identified as design variables to reduce weight while meeting stress and deformation constraints. After iterative optimizations, the final design reduced weight by 15% while improving stress distribution and lowering maximum deformation to satisfy project objectives.
