Design and Buckling Analysis of Connecting Rod

IJERT-International Journal of Engineering Research & Technology, 2021

Connecting rod plays a crucial role in the working of an IC Engine, whose key role is to transmit power from the piston pin to the crankpin. It basically acts as a rigid link and transmits the reciprocating motion of the piston to the rotational motion of the crankshaft. It is a slender part with its length considerably greater than its width. It is mainly subjected to axial compressive stress. In this paper, we have considered a 4-stroke single cylinder IC Engine of 66 mm bore diameter and 99 mm stroke length, and calculated the required dimensions. We have modelled the Connecting rod using SOLIDWORKS software, and carried out Static and Buckling Analysis in ANSYS software.

Buckling Analysis Of Connecting Rod

The connecting rod is the transitional part between the piston and the crankshaft. Its essential capacity is to transmit the push and pull from the piston pin to the crank pin, in this way changing over the reciprocating motion of the cylinder into turning movement of the crank. The capacity of connecting rod is to transmit the push of the piston to the crank shaft, and as the outcome the reciprocating motion of the piston is interpreted into rotational movement of the wrench shaft. It comprises of a pin-end, a shank section and a crank end. Pin end and crank end pin holes are machined to allow exact fitting of bearings. In this thesis, a connecting rod is demonstrated utilizing catiav5, discretization utilizing HyperMesh and analysis utilizing Nastran. The outcome predicts the most extreme buckling load and basic locale on the interfacing pole. It is imperative to find the basic territory of concentrated stress for fitting adjustments. To discover the stresses created in interfacing pole under static loading with various stacking states of compression and tension at crank end and pin end of connecting rod.

Connecting rod is a transitional part between piston and crankshaft converting reciprocating motion of piston into rotational movement of the crank. It comprises of piston end, crank section and crank end. Interfacing rods are subjected to forces generated by mass and fuel combustion. These two strengths result in axial load and bending stresses. It undergoes high cyclic loads which range from high compressive loads due to combustion; to high tensile loads due to inertia. For the improved engine performance connecting rod must have the highest possible rigidity at the lowest weight. This study includes design and analysis of four wheeler connecting rod. In this paper, firstly proper geometrical model was developed using UG NX10.0. Geometry is taken from the literature [1]. The stresses were found in existing connecting rod for the given loading conditions using FEA software ANSYS 11.0. The analysis was carried out on two different materials such as forged steel, Aluminum 7075 and re...

Buckling Analysis of Connecting Rod to the Shank Sectional Area Reduction of Variable Cross Section by using Finite Element Method

International Journal for Scientific Research and Development, 2015

A connecting rod is an engine member which is subjected to alternating direct compressive and tensile forces. Since the compressive forces are much higher than the tensile force, therefore the cross-section of the connecting rod is designed as a different cross section and the rankine formula is used. A connecting rod subjected to a cyclic as well as axial load W may buckle with x-axis as neutral axis in the plane of rotation of the connecting rod, or y-axis is a neutral axis In our analysis, Ansys Static Structural and Linear Buckling was used a model was developed on NX-5. In order to verify the present Ansys model, the slenderness ratio and the critical buckling stress, radius of gyration are compared with the available experimental results present in the literature and the design of X-section connecting rod having different shank cross section width.i.e.26mm,25mm,24mm,23mm,22mm. In this analysis, the simulations of X-section connecting rod at static load of 64.7 KN and the confi...

International Journal of Engineering Research and, 2016

The intermediate component between crank and piston is known as connecting rod. The objective of connecting rod is to transmit push & pull from the piston pin to the crank pin and then converts reciprocating motion of the piston into the rotary motion of crank. The components are big shank, a small end and a big end. The cross section of shank may be rectangular, circular, tubular, I-Section, +section or ellipsoidal-Section. It sustains force generated by mass & fuel combustion. The resulting bending stresses appear due to eccentricities, crank shaft, case wall deformation & rotational mass. FEA approach deals with structural analysis along with various parameters which affects its working & define best solution to overcome the barriers associated with it. This thesis describes designing and Analysis of connecting rod. Currently existing connecting rod is manufactured by using Carbon steel. In this drawing is drafted from the calculations. A parametric model of Connecting rod is modelled using CATIA V5 R20 software and to that model, analysis is carried out by using ANSYS 13.0 Software. Finite element analysis of connecting rod is done by considering the materials, viz... For C70 Steel, Belgium. The best combination of parameters like Von misses Stress and strain, Deformation, Factor of safety and weight reduction for two wheeler piston were done in ANSYS software. Structural steel has more factor of safety, reduce the weight, increase the stiffness and reduce the stress and stiffer than other material like carbon steel. With Fatigue analysis we can determine the lifetime of the connecting rod.

The connecting rod (CR) is the main moving parts and an important component of engine. The connecting rod is the intermediate member between the piston and the Crankshaft. Its primary function is to transmit the push and pull from the piston pin to the crank pin, thus converting the reciprocating motion of the piston into rotary motion of the crank. The main objective of this study is to explore weight reduction opportunities for a production forged steel connecting rod. In this project, finite element analysis of single cylinder four stroke petrol engines is taken as a case study; Structural systems of connecting rod can be easily analyzed using Finite Element techniques. So firstly a proper Finite Element Model is developed using Cad software Pro/E. Then the Finite element analysis is done to determine the stresses in the existing connecting rod for the given loading conditions using Finite Element Analysis software. Based on the observations of the static FEA and the load analysis results, the load for the optimization study was selected. The results are also used to determine degree of stress multiaxiality, and the fatigue model to be used for analyzing the fatigue strength. Outputs include fatigue life, damage, and factor of safety.
