Abstract:-The knuckle joint, a crucial component in the steering system, is located between the steering rod
and the pinion of the steering gear. This joint is designed to be easily disconnected when necessary. The
stress experienced by the knuckle joint is influenced by the design of the stub and the materials used for the
assembly components, which include the knuckle, stub, and arm. This research focuses on improving the
design of the stub using the response surface method (RSM).
In this study, the stub design was developed and analyzed using the ANSYS FEA (Finite Element Analysis)
software package. The analysis revealed that the safety factor for the stub in the base design is 3.54, while
for the knuckle, it is 4.15. These safety factors indicate the design's robustness and reliability under
operational stresses.
To further enhance the design, response surface optimization techniques were applied. Before optimization,
the maximum mass of the stub was 0.61046 kg. After optimization, the minimum mass achieved was 0.59352
kg, representing a 2.77% reduction in weight. This reduction not only contributes to material savings but
also potentially improves the overall performance and efficiency of the steering system by reducing the load
on the joint.
