DESIGN AND MODAL ANALYSIS OF AUTOMOTIVE CRANKSHAFT FOR MATERIAL OPTIMIZATION USING ANSYS WORKBENCH
Publication Date : 02/09/2019
Abstract— Crankshaft is one of the most important parts in internal combustion engine, which converts the reciprocating displacement of the piston to a rotary motion. Finite element analysis (FEA) is performed to obtain the variation of stresses. The linear static and modal analysis will be conducted using FEA Software ANSYS. Linear Static and Modal Analysis will be conducted on the crankshaft with three different materials like Static Structural, Chilled Cast Iron, Titanium Alloy and Aluminum Alloy to obtain variation of stresses and deformations in the crankshaft. The Von-Mises Stresses induced in the crankshaft with Titanium Alloy and Aluminum Alloy is lesser than Structural Steel and Chilled Cast Iron. Natural frequencies has been plotted by performing Modal Analysis. In this project Aluminum Alloy 6061 has been suggested for crankshaft for better performance compared to other materials. The FE result validations has been done by theoretical calculations.
