Diesel Engine Connecting Rod Design, Development and Analysis Using CAE Tools

An important component of an engine is the connecting rod, which is constructed of
C-70 alloy steel. by taking composite material into account. Finite element analysis is
used to determine the ideal arrangement of parameters for connecting rods, including
deformation, Von Mises stress, and weight reduction. To determine the best
connecting rod design, I-section and H-section are subjected to finite element analysis.
With the aid of the ANSYS 14 Workbench programme, finite element analysis is
carried out. In CATIA V5.0 software, the appropriate CAD model is created for this

function. By comparing the static analysis of connecting rods with various cross-
sections made of the same material, it was possible to determine that the maximum

stress for the connecting rod I-section is lower than that of H-section. To examine the
fatigue strength of the connecting rod, fatigue failure analysis is also carried out. To
calculate the safety factor, life, stress and damage of the connecting rod, a fatigue tool
is utilised.
