Singh2, Shivani3 1M. Mechanical Engineering Dept. By applying the boundary conditions on connecting rod the unknown variables such as stress, deformation, strain are found using the FEA based software ANSYS. Together with the crank, it forms a simple mechanism that converts reciprocating motion intorotating motion. A connecting rod may also convert rotating motion into reciprocating motion, its original use. Earlier mechanisms, such as the chain, could only impart pulling motion.

Being rigid, a connecting rod may transmit either push or pull, allowing the rod to rotate the crank through both halves of a revolution. Today, the connectingrodisbest known through its use in internal combustion piston engines, such as automobile engines. Measurements for which were taken practically with the help of a Caliper Scale. The engine specifications of Bajaj Discover are below in the table.

Actual photograph of Bajaj Discover cc Connecting Rod. Table Specifications of Bajaj Discover Power 8 bhp rpm Max. Dimension Value Overall length mm Max. Cast iron is also used but due to its heavyweightmanufacturersoftenavoidit.

Initial sketch of the connecting rod. Final extruded Isometric view of the connecting rod. Applying fixed support to the model. Applying load to the model. Total Deformation in Aluminum T6.

Equivalent Elastic Strain in Aluminum T6. Equivalent sress in Aluminum T6. Equivalent Stress in Aluminum T6. Total Deformation in structural steel. Equivalent strain in structural steel. Equivalent stress in structural steel. Result and Discussion: The big end of the connecting rod was fixed whereas a load of N was applied on the small end, then Meshing of the model was performed.

Different materials were applied one by one and solution was obtained for Total Deformation, Equivalent Elastic Strain, Equivalent Stress. From analysis we found the mass of the connecting rod by applying different materials are: 4. Statistics of Meshing used for analysis.

Comparison table of all the applied materials. Materials Total Deformatio n mm Max. Graph - 2 Comparison of Max. Equivalent Elastic Strain of different materials. Graph - 3 Comparison of Max.

Equivalent stress of different materials. The connecting rod which is made of aluminum alloy chosen for this project belongs to Bajaj Discover cc bike. The results obtained after performing the analysis shows the difference in the structural behavior of theconnectingrod. It is concluded that structural steel shows least stress, strain and deformation on same static load condition. Butdueto its heavy weight it cannot be considered. Also the generally used aluminium alloys are cost efficient due to their large market and higher production, so the composite aluminium with silicon carbidemayincreasethecost.

Also, because of the same reason explicit dynamic analysis could not be performed which could have shown a more close real to life analysis of the connecting rod. So, for future work, a higher mesh setting can be applied for analysis and explicit dynamic analysis can be performed.

A connecting rod , also called a con rod , is the part of a piston engine which connects the piston to the crankshaft. Together with the crank , the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston, and rotate at both ends. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. The earliest evidence for a connecting rod appears in the late 3rd century AD Roman Hierapolis sawmill. It also appears in two 6th century Eastern Roman saw mills excavated at Ephesus respectively Gerasa.

Connecting rod

Kakaee, M. Shojaeefard, J. The performance of a spark ignition engine is investigated under different values of ignition advance. By varying the ignition timing, the results of some characteristics such as power, torque, thermal efficiency, pressure, and heat release are obtained and compared.

Show all documents It connects the piston to the crankshaft and is responsible for transferring power from the piston to the crankshaft and sending it to the transmission. There are different types of materials and production methods used in the creation of connecting rods.

BMEP: An important performance yardstick

A large majority of light-duty vehicles in the United States are powered with spark-ignition SI engines fueled with gasoline. Several technologies have been developed to improve the efficiency of SI engines. This chapter updates the status of various SI engine technologies described in the National Research Council report that focused on reduction of fuel consumption NRC, As stated in Chapter 2 of the present report, the objective is to evaluate technologies that reduce fuel consumption without significantly reducing customer satisfaction—therefore, power and acceleration performance are not to be degraded. The primary focus is on technologies that can be feasibly implemented over the period to

We have presented the topics of Thermal Efficiency and Volumetric Efficiency as methods for estimating the potential output of a given engine configuration. Brake Mean Effective Pressure BMEP is another very effective yardstick for comparing the performance of an engine of a given type to another of the same type, and for evaluating the reasonableness of performance claims or requirements. The definition of BMEP is: the average mean pressure which, IF imposed on the pistons uniformly from the top to the bottom of each power stroke, would produce the measured brake power output.
