Abstract: The fundamental objective of this study is to design and create a connected rod
structural element. The connecting rod is a vital machine part in every engine, serving as the
principal link between the piston and the crankshaft. The connecting rod has two key purposes in
a system engine: it receives input load from the piston and transmits power to the crankshaft. The
study proposes that all significant components of system design and process convergence be
investigated, beginning with analytical modeling and concluding with simulation. This is done to
provide more realistic and long-lasting system design and process optimization outcomes.
Material selection, a factor of safety analysis, static and dynamic stress analysis, kinematics, and
kinetics analysis are all performed to provide a more viable and long-lasting output. CAD
modeling is used with ANSYS simulation to provide more viable and convergent outcomes.
It is vital to take into account a variety of complex loads applied on the connecting rod during
operation. These loads include high tensile loads resulting from inertia and a strong compression
force resulting from fuel compression. Additionally, the connecting rod is bent by the thrust and
centrifugal forces acting on it. As a consequence, our research focused on gradually increasing the
cross-sectional area of the connecting rod to conduct an in-depth examination of buckling under a
variety of loads and stresses. We concluded from our analysis that the bigger end of the
connecting rod is exposed to more stress than the smaller end. To allow stress to be transferred to
the connecting rod's center from the shank's reduced cross-sectional area over time, the shank's
cross-sectional area gradually lowers over time. The topology is utilized to optimize the geometry
of the connecting rod.

I. INTRODUCTION
Connecting rod is a dynamic component of internal combustion engine, and it is subjected to time-
varying axial and bending loads. The working principle of connecting rod is very much complex,
that it is often subjected to complex loads such as power thrust from piston pin, inertia force, and
high compression loads. The connecting rod has to be designed in such a way so that it should
withstand these various complex and cyclic loading conditions. Hence, the connecting rod must have
good mechanical properties like strength and rigidity as well as should be light in weight. The basic
function of connecting rod is to transmit the thrust of a piston to the crankshaft, by translating the
reciprocating motion to rotational motion. In an internal combustion engine, connecting rod forms a
