Conventional Design and Static Stress Analysis of IC Engine Component (Crank Pin) Using the Finite Element Method

Rahul Kumar, Tushar Gupta and Rajesh Bajaj

The main objective of this study is to analyse performance of an internal combustion engine components to obtain detailed information of stress/strain distributions. Component that is analysed crankpin. This study deals with two subjects, first, conventional design of the components, and second, static stress analysis of the components using the finite element method. Component geometry is obtained using conventional design methods. The loads acting on the component as a function of time are obtained. Two-dimensional static finite element analysis is performed at several positions and by varying the number of elements. The stress distributions of the components are illustrated in the form of graphs and the various results are studied comparatively. Design and analysis are done with the help of MATLAB programs which have been included in the study. It is the conclusion of this study that the finite element method can be used to compute localised stresses and results achieved from aforementioned analysis can be used in optimization of the components.
