Failure Strength of Automotive Steering Knuckle Made of Metal Matrix Composite

This article presents the static performance of composite steering knuckle due to drive on an equivalent road, including different types roughness and maneuvers. To achieve this purpose, driving a full-vehicle model was simulated using multi-body dynamics (MBD) method, imposed loads connection points components suspension system were extracted considering various Next, CATIA software used prepare smooth by employing coordinate measuring machine (CMM) data. Stress analysis performed under maximum value loading history in finite element (FE) software. Eventually, safety factor calculated based some well-known criteria for failure materials. Moreover, optimum tungsten carbide as reinforcing substance aluminum estimated increase strength. The results show that leads strength purely axial (normal stress criterion) also decrease part shear (shear criterion). Therefore, nature (i.e., multi-axial non-proportional random amplitude conditions) applied automotive actual conditions, metal matrix (aluminum reinforcement) is not practical.
