Design Evaluation and Optimization of Connecting Rod Parameters Using FEM

The main objective in the “Design evaluation and optimization of connecting rod parameters by using finite element method” is to achieve suitable design for connecting rod. That can be achieved by changing such design parameters in the existing design.

Finite element analysis of single cylinder four stroke petrol engines is taken for the study; Structural systems of Connecting rod can be easily analyzed using Finite Element techniques. So firstly a proper Finite Element Model is developed using Cad software Pro/E Wildfire 4.0. Then static analysis is done to determine the von Misses stress, shear stress, elastic strain, total deformation in the present design connecting rod for the given loading conditions using Finite Element Analysis Software ANSYS v 12. In the first part of the study, the static loads acting on the connecting rod, After that the work is carried out for safe design.

Based on the observations of the static FEA and the load analysis results, the load for the optimization study was selected. The results were also used to determine of various stress and the fatigue model to be used for analyzing the fatigue strength. Outputs of the fatigue analysis of include fatigue life, damage, factor of safety, stress biaxiality indication. Then results of present model in ANSYS are compared with the results of existing design in the reference paper.
