Connecting rod is engine component which transmits motion from piston to the crankshaft and serves as lever arm. The function of connecting rod is to convert piston’s reciprocal movement into rotary motion of the crankshaft. Connecting rod generally made from Carbon steel and Aluminium alloys have been used in recent days and some different materials are finding it’s application. The performance connecting rod in automobile engine is influenced by it’s design and weight for production of durable, cheaper and light connecting rod, hence optimization and analysis of connecting rod. The 3D model of connecting rod is designed and developed using CATIA V5. In proposed approach different materials compared like Aluminium alloy 7075, Magnesium alloy, Titanium alloys (Ti -3Al- 2.5V) and beryllium alloy (25) are taken for the analysis of connecting rod and factors like Stress, Strain and Deformation were obtained. The purpose of this study is identify best materials for connecting rod, after analysing at ANSYS APDL 15.0. KEYWORDS : Connecting rod, CATIA V5, ANSYS APDL15.0, Aluminium alloy 7075, Magnesium alloy, Titanium alloy (Ti-3Al-2.5V) and Beryllium Alloy (25).

The Core

A connecting rod is the core component of an engine which has a function to transmit power released from combustion from the piston to the crankshaft. Deformation is the most commonly occurring damage to connecting rods. The connecting rods made of structural steel, aluminium alloy and titanium alloy were designed using Autodesk Inventor and analysed using ANSYS. The simulations showed the following results. The connecting rod made of structural steel had the highest maximum stress of 82.791 MPa. The connecting rod made of aluminium alloy had the highest maximum deformation of 0.84071 mm. The three connecting rod materials had the same maximum safety factor, i.e. 15.

The material herein presented was gathered as part of a research project for the Bureau of Aeronautics (Structures Branch) of the U.S. Navy on “Evaluation of High Strength Aluminium Alloys.” The Bureau has released this material for independent publication.In this paper the physical constants determined are limited to elastic limit, yield stress, ultimate stress, modulus of elasticity, weight and ductility. The materials tested are primarily the new aluminium alloys 75 ST, R 301 T, and R 303 T.To offer an immediate basis of comparison for aluminium alloys, the aluminium alloy at present in common use, namely 24 ST, was also tested. To extend the scope of the project still further, a few tests on magnesium alloy and stainless steel were included.

This article presents an experimental investigation aimed to obtain the optimum formability of light-weight alloys under the multi-stage forming process. Titanium alloy sheets (Ti-6Al-4V) and aluminium alloy sheets (AA5052) of thickness 1 mm with different widths (i.e. 20, 90, and 110 mm) are selected as forming specimens. In order to carry out the multi-stage forming process, a special fixture with a heating system for the pre-straining process is designed and manufactured. The limit dome heights of both titanium alloys and aluminium alloys are measured and recorded. The experimental results reveal that both of the light-weight alloys yielded enhanced ductility at higher working temperatures, because of a decrease in the yield strength. The formability of selected materials is found to be sensitive to the forming temperatures and multi-stage forming processes.

Homogenisation Process

When extruding the casted rods from EN AW 2011 aluminium alloys, not only their homogenized structure, but also their extrudable properties were significantly influenced by the hardness of the alloy. In this study, the object of investigations was the EN AW 2011 aluminium alloy, and the effect of homogenisation time on hardness was investigated. First, homogenisation was carried out at 520 °C for different times, imitating industrial conditions. After homogenisation, the samples were analysed by hardness measurements and further characterised by microscopy and image analysis to verify the influence of homogenisation on the resulting microstructural constituents. In addition, non-equilibrium solidification was simulated using the program Thermo-Calc and phase formation during solidification was investigated. The homogenisation process enabled more rounded shape of the Al2Cu eutectic phase, equilibrium formation of the phases, and the precipitation in the matrix, leading to a significant increase in the hardness of the EN AW 2011 aluminium alloy. The experimental data revealed a suitable homogenisation time of 4–6 h at a temperature of 520 °C, enabling optimal extrusion properties.

Interference Fit

Current design procedures for complicated three-dimensional structural components with component interactions may not necessarily result in optimum designs. The wrist pin end design of the connecting rod with an interference fit is governed by the stress singularity in the region where the wrist pin breaks contact with the connecting rod. Similar problems occur in a wide variety of structural components which involve interference fits. For a better understanding of the problems associated with obtaining optimum designs for this important class of structural interaction only the design problems associated with the wrist pin end of the rod are addressed in this study. This paper demonstrates a procedure for designing a functional and minimum weight wrist pin end of an automobile engine connecting rod with an interference fit wrist pin. Current procedures for Finite Element Method (FEM) model generation in complicated three-dimensional components are very time consuming especially in the presence of stress singularities. Furthermore the iterative nature of the design process makes the process of developing an optimum design very expensive. This design procedure uses a generic modeler to generate the FEM model based on the values of the design variables. It uses the NASTRAN finite element program for structural analysis. A stress concentration factor approach is used to obtain realistic stresses in the region of the stress singularity. For optimization, the approximate optimization strategy in the COPES/CONMIN program is used to generate an approximate design surface, determine the design sensitivities for constrained function minimization and obtain the optimum design. This proposed design strategy is fully automated and requires only an initial design to generate the optimum design. It does not require analysis code modifications to compute the design sensitivities and requires very few costly NASTRAN analyses. The connecting rod design problem was solved as an eight design variable problem with five constraints. A weight reduction of nearly 27 percent was achieved over an existing design and required only thirteen NASTRAN analyses. It is felt that this design strategy can be effectively used in an engineering environment to generate optimum designs of complicated three-dimensional components.
