The main objective of this study is to explore weight and cost reduction opportunities in the design and production of a connecting rod. This can be achieved by performing a detailed load analysis. A study is performed on a steel connecting rod. Reduction in machining operations, achieved by change in material, is a significant factor in manufacturing cost reduction. This paper deals with the study of weight reduction performed under two cyclic loads comprising dynamic tensile and static compressive as the two extreme loads. The fatigue strength is the most significant factor in the process. The study analysis includes the determination of loads acting on the connecting rod as a function of time for finding out the minimum stress area to remove the material. The connecting rod can be designed and analysis under a load ranging from tensile load, corresponding to various degree crank angle at the maximum engine speed as one extreme load, and compressive load corresponding to the peak gas pressure as the other extreme load. Furthermore, the existing connecting rod material can be replaced with a new composite material, the fracture crack ability feature, facilitates separation of cap from rod without additional machining of the mating surfaces. Also the same performance can be expected in terms of component durability.
