Modeling And Optimization Of Single Piston I.C Engine Crank Shaft With Different Materials And Loads By Using Fea

Abstract

Crankshaft is a component in an engine which converts the reciprocating motion of the piston to the rotary motion. Where as in a reciprocating compressor, it converts the rotational motion into reciprocating motion. In order to do the conversion between two motions, the crankshaft has "crank throws" or "crankpins", additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach. The design of a crankshaft is of 4 stroke single cylinder S.I engine. So that two revolution of crankshaft for each stroke. The peak pressure acting on the engine crankshaft. The crankshaft of the located model is designed using CAD SOFTWARE CATIA V5 with the accurate dimensions and material standards. CATIA V5 is one of the best design software in design tools were we can easily design components based on it dimensions and analysis in annoys with accurate results. In this project to compare the optimization of crank shaft on two different materials(  aluminum alloy & e-glass epoxy composite)  .The results are taken and evaluated with the given load conditions and following deformation results are shown.
