CAE ANALYSIS ON A FORD ECOBOOST MUSTANG CONNECTING ROD FOR FORGED STEEL, ALUMINUM 7075

Abstract

Connecting rod is high volume production critical component in an automobile engine. Every Internal combustion engine uses a connecting rod. Connecting rod must have highest possible rigidity with lowest possible weight. The major stress developed in the connecting rod are axial stress, due to combustion chamber pressure, and bending stress, due to centrifugal effect. Connecting rod mainly fails due to fatigue; according to survey, about 90% of the time the failure is due to fatigue. CAE analysis on Ford Eco boost Mustang connecting rod is carried out to validate the life of the connecting rod for forged steel and Aluminium7075. CAE analysis is mainly aimed at the static structural case and fatigue life case using ANSYS workbench. Fatigue redesign is proposed wherever necessary. Results of CAE is compared between forged steel and Aluminium 7075 to conclude the best material to use for a Ford Eco Boost Mustang.
