Connecting rod is an important intermediate between piston and Crankshaft.Connecting rod transmits piston load to the crank causing the latter to turn, thus converting the reciprocating motion of piston into rotary motion of the crank. Connecting rods are subjected to static and dynamic loading forces generated by mass and fuel combustion. It undergoes high cyclic loads of the order of 10 8 to10 9 cycles, which ranges from high compressive loads due to combustion, to high tensile loads due to inertia. The connecting rod has been the topic of research for the aspects such as production, performance simulation, materials etc. This paper describes Design, modeling and analysis of connecting rod. The main aim of paper is to analyze static stresses developed in connecting rod i.e. compressive stress and tensile stress, to explore weight reduction possibilities for the production of connecting rods. The material used for the purpose is Aluminum Metal Matrix. The comparative study is done between steel and AMC connecting rods. Therefore, study has been divided in two subjects, first, static stress analysis of the connecting rod and second, optimization of weight of connecting rod.

... According to Yogesh N Dupare [5], He also says that axial stress is due to combustion chamber pressure and inertia forces and bending stress is due to centrifugal action of the connecting rod when connected to the crank shaft. Tony George Thomas [6] adds that fatigue failure is very high due to the fluctuation of these loads. Yogesh [5] says that 50-90% of the failure of the connecting rod are due to fatigue failure, thus it is very important to consider fatigue failure in the connecting rod design and great care must be taken by the Computer aided Engineering (CAE) team in a company to perform analysis on fatigue and come up with the redesign proposal, if necessary. ...

Connecting rod works as an intermediate link between piston and crankshaft. The function of connecting rod is to convert reciprocating motion into rotary motion. Since it is subjected to variable tensile and compressive load, it should be strong enough to bear that load. Manufacturing of connecting rod is one of the most important parameter that can affect the overall performance of connecting rod. Selection of connecting rod for good performance of engine is very difficult. There are various factors that are to be considered before selecting connecting rod, like type of engine, maximum rpm engine produces, requirement of relative weight, stiffness and strength of connecting rods, type of cross section like I-section, H-section, Rectangular or circular, material of connecting rod etc. After selecting the appropriate cross section, the material used in the connecting rod should be chosen wisely because during manufacturing process it has to undergo various production processes and subsequent heat treatment process, which is very much important for strength and stiffness. In this paper, a review has been attempted on selection parameter of connecting rod like cross section, manufacturing process and material selection which can enhance the performance of engine.

Connecting rod is a major link which connects the piston to the crankshaft and is responsible for transferring the power from the piston to the crankshaft. In this paper Finite element analysis of connecting rod used in single cylinder four stroke petrol engines is taken for the study. Static stress analysis is conducted on connecting rod made up of two different materials viz. E-glass/Epoxy and Aluminium composite reinforced with Carbon nanotubes. Modelling and comparative analysis of connecting rod is carried out in commercially used FEM software ANSYS 14.0.

The connecting rod is a vital component of any engine, which undergoes several stresses while in motion. The design of this component is very crucial to improve the durability of the engine and the mechanical efficiency of it. The main objective of this paper is to perform a modal analysis for the connecting rod for different materials as well as perform a kinematic analysis to verify their motion characteristic complies with the standard motion. The modal analysis helps in finding the natural frequency for the geometry of connecting rod for different materials. We are focusing in reducing the weight of the connecting rod by choosing the appropriate material that is safe and suitable for the task. Reducing the weight of the connecting rod not only improves the overall efficiency of the engine but also saves cost and unnecessary balancing weights for the rod. The requirement of strength for the connecting rod is preferred to make it durable.
