Bending stress and fatigue analysis of connecting rod of through fine element method
Abstract
In recent years the need to predict how a product will perform over the life cycles has increased. Aerospace and other industries need to demonstrate the durability of designs and plan effective maintenance schedules. The growth of cracks due to fatigue loads plays an important role in limiting the life of products. In this paper, a new method is presented for the automatic growth of edge cracks in three-dimensional fracture analysis using BEM. The procedure described overcomes the current problems with crack growth analysis that currently has to be performed manually. Applications are presented whichdemonstrate the effectiveness of the technique.
The main objective of this work is to assess static and dynamic characteristics of a crank shaft under different load conditions. Geometric modeling of the various components of crankshaft has been carried out in part mode as 3-D models using UNIGRAPHICS-NX 4. The properties, viz. crossectional area, beam height, area moments of inertia of these 3-D modeled parts are estimated in UNIGRAPHICS-NX 4. These properties have been used as input while performing the Finite Element Analysis using ANSYS work bench
