FINITE ELEMENT ANALYSIS OF CRANKCASE

Abstract

In an internal combustion engine of the reciprocating type the crankcase is housing for crankshaft. Crankcase is main building block of engine. The enclosure form the large cavity in the engine and it is locate below cylinder or cylinders head which in multi cylinder engine is usually integrated into one or more cylinder block. In this paper analysis investigation has been conducted on the crankcase of four cylinder engine. In this paper static analysis and modal analysis is done through ANSYS software. A static analysis is use to find total deformation, stress, strain of crankcase caused by pressure. In modal analysis natural frequency find out. In analysis for component material is important so for crankcase gray cast iron is used. This paper shows that crankcase is well safe state and under the yield strength range at particular pressure.
