MODAL ANALYSIS OF CONNECTING ROD WITH DIFFERENT MATERIALS USING ANSYS

In an automobile engine, the connecting rod is one of the most crucial components. Between the piston and the crankshaft, the connecting rod serves as a link. Its main job is to transfer the push and pull from the piston pin to the crank pin, transforming the piston’s reciprocating motion into the crank’s rotating motion. Internal engine connecting rods are typically made of steel and aluminium alloys (for light weight and high impact load absorption) or titanium (for higher performance engines at a higher cost) or composite materials. Composite materials are made up of two or more constituent materials with significantly different physical or chemical properties that, when combined, produce a material with characteristics that are distinct from the individual components. Within the finished construction, the constituent components stay separate and distinct. For a variety of reasons, the new material may be preferred: Materials that are stronger, lighter, or less expensive than standard materials are common examples. This research investigates the finite element analysis of connecting rods used in single-cylinder four-stroke petrol engines. Connecting rods made of various materials, such as medium carbon steels, aluminium alloys, and magnesium alloys, are subjected to modal analysis. The connecting rod is modelled in SOLIDWORKS and compared using the commercially available FEM programme ANSYS Software. By securing the piston end and applying load to the connecting rod’s crank end, a modal analysis was performed. Total deformation for the given loading conditions is the output parameter in Modal analysis.
