Analysis of Crankshaft

Pratiksha M. Nargolkar

Abstract: Crankshaft is the most imperative, outsized and exposed component of an internal combustion engine. In this work a 4-cylinder diesel engine crankshaft is used for analysis. For analysis a crankshaft is modeled using software PRO-E and further analyzed by using software Ansys R15.0. FEA method is used to conduct static as well as dynamic analysis of the crankshaft in which the torque is applied on the drive end. Various analysis on the crankshaft are conducted, such as Equivalent principal elastic strain, Maximum shear stress, Equivalent Von misses stress. The analysis will be carried out to obtain the variation of stress magnitude at critical locations. Drive end, rear end and other critical locations of the connecting rod are targeted based upon the industrial practices and the literature review surveyed. Based upon the results obtained some critical conclusions will be derived. As a comparative stress analysis for both static as well as dynamic cases will be performed, stress distribution and response levels will be linked together with the help of the results obtained. These results will be additionally compared with theoretical results with the help of failure theories. Detailed insight will be provided for future research and developments in the field of crankshaft.

Keywords: Crankshaft, Crankpin, FEA, Static analysis, Dynamic analysis, Theoretical analysis.
