Stress and deformation analysis of a connecting rod by using ANSYS

Öz

The connecting rod is the intermediate component between the piston and the crankshaft, and its primary function is to move the up and down from the piston pin to the crankshaft converting the reciprocating motion into rotary motion of the piston and crankshaft. This study describes a numerical analysis of connecting rod for determining the critical stress regions. During the analysis of connecting rod, loads corresponding to different engine speeds were assumed to be statically applied, and their corresponding stress and deformation values were evaluated. The power and torque values of engine were utilized to be used as the load boundary conditions in static simulation model, other parameters those of used as input values were geometric dimensions of connecting rod and its material properties. Numerical analyses were performed for the connecting rod made of SS 304 material. A 3D CAD model was developed for the connecting rod through the SOLIDWORKS software, then drawn solid model was transferred to the ANSYS software with Workbench module. Von mises stress and deformation analyses were evaluated under the different engine speeds with indicating that connecting rod did not failure and fractured under the applied external loads.
