The presence of variability in physical attributes and manufacturing processes is a key issue in the automotive business. Deterministic techniques cannot account for these variations without resulting in large structures. The need to evaluate a design's resilience necessitates an approach based on durability and design optimization via probabilistic models of design variables (DOE). The steering knuckle is one of the important components of the vehicle that connects the suspension, steering system, wheel hub, and brake to the chassis. The process of optimizing the design employing a methodology based on durability and design optimization through probabilistic models of design variables has been characterized as the aforementioned problem (DOE) The major function of the knuckle on a car is to load and steer, which supports the body weight, transfer switch to bear the front brake torque and braking torque and so on. . As a result, the contour of the structure and the mechanical properties of the knuckle are held to high standards. Models can be split into heavy-duty vehicles and light-duty vehicles. midsize car steering knuckles, light vehicle steering knuckles, mini-cars Passenger vehicles, knuckle cars, and knuckle cars forged knuckle into cast Aluminum and cast iron steering knuckles three pieces; their characteristic shape into pole class knuckle, knuckle class Centre hole, and casing class; press materials and manufacturing processes employed forged knuckle into cast Aluminum and cast iron steering knuckles Pole class knuckle mainly consists of the stem portion, flanges and branches rights, and more generally for large Mid-sized cars and buses in; Centre hole category mainly consists of the base knuckle Centre hole category consists mainly of the base knuckle, flange and right branches, the base Centre hole, and more generally for large Mid-sized cars and buses in; Centre hole identification and characterization consists of the base knuckle, flange and right branches, the base Centre hole, and more generally for large Mid-sized cars and buses in; Generally used for driving a car with a front axle that is made up mostly of pole, sleeve, and flange components. CATIA software is used to design the steering knuckle component, and ANSYS WORKBENCH is used to perform the static structural analysis. We ran simulations on three different materials, Stainless Steel, AL alloy, and Gray cast iron, by altering the mesh size (element size) to 10mm, 8mm, and 6mm, respectively, for better results and comparison.
