Description
Summary:Titanium alloys have created a niche in mechanical parts that requires high strength with light-weight. Nowadays, parts of exotic vehicles are made from titanium alloys which contribute to the high cost of these cars. Shape and model optimization have played important roles in cost reduction in contrast to the choice of high-end materials usually as a factor of the weight. This work considers the impact of shape optimization on Ti-6Al-4 V used as connecting rod in a 500 cc engine. A model of the connecting rod was created using Autodesk Inventor; the various forces and constraints were calculated which were then used in ANSYS to simulate the failure. Shape optimization was achieved by optimizing the clearance at the crank end. The optimized model yielded 11.7% reduction in weight, lower deformation and stress distributions. It was discovered that shape optimization by modifying the clearance at the crank end offered the best output.
