Abstract

Crankshaft is one of the vital components for the effective and precise working of Internal Combustion engine with the complex geometry; which converts the reciprocating displacement of the piston to a rotary motion. The crankshaft consists of three parts i.e. crank pin, crank web and shaft. In the present work, I have done a crankshaft analysis to choose the best material for the crankshaft. Firstly, I have prepared a crankshaft model in the CAD software SOLIDWORKS and them SOLIDWORKS file saved ion the STEP format because ANSYS software can only read the STEP file format. In the ANSYS software 3.5 MPa load apply on the crankshaft for analysis, three-time analysis is done of the crankshaft load was the same for three times but the material was changed. The three material used in this research from the survey is Aluminium Alloy, Alloy Steel, Structural Steel. Mainly two factors are found out stress and deformation for material comparison. Tetrahedron meshing method is used for the crankshaft meshing. After meshing the nodes of the crankshaft are 5664 and elements are 3118. Both the Rear and front main bearing journal are kept fixed and load is applied on the upper face of the main bearing journal. In the end, I have found out that if stress is the main factor for crankshaft failure then Aluminium Alloy is the best material for the crankshaft because in this material less stress produced as compared to the other materials.
