Analysis of Connecting Rod to determine Factor of Safety & Critical Buckling Stress by using Finite Element Method

The effective uses of a connecting rod are limited at its maximum strengthening limits. The study was conducted by using the Finite element method. The connecting rod is used with flow of with rotation such as internal combustion engines and reciprocating pumps and compressors. The major study was done on connecting rod by using C70S6 material with different middle thickness &side width. A factor of safety was analyzed and static structural & linear buckling is performed for validation. In our analysis, ANSYS was used and the model was developed on UniGraphics. In order to verify the present ANSYS model, the critical buckling with their deformation by using C70S6 material are compared with the available experimental results present in the literature. And the design of connecting rod with different middle thickness (5.5,5.4,5.3,5.2,5.1) & side width (6.0,6.1,6.2,6.3,6.4). In this study, the simulations of different middle thickness &side width, was analyzed for factor of safety and the configurations of connecting rod are proposed. The results show that increasing side width and decreasing middle thickness increases radius of gyration and factor of safety for each location of connecting rod and decreases the slenderness ratio with increase in a side width simultaneously. The factor of safety of the connecting rod is compared by using four types of profiles i.e. middle thickness (5.5,5.4,5.3,5.2,5.1) & side width (6.0,6.1,6.2,6.3,6.4) of optimized connecting rod for various location.
