Abstract
The crankshaft is an important and large component of an engine. The function of crankshaft is to converts the reciprocating displacement of the piston into a rotary motion. In this paper, the stress analysis and modal analysis of a 4-cylinder crankshaft are discussed using finite element method. The 3D model of crankshaft was developed in PRO/E and imported to ANSYS for strength analysis. In this study, failure analysis of a crankshaft was carried out. Several causes are there to failed the crankshaft. All crankshafts were failed from the same region. Failures had occurred in the first crankpin, the nearest crankpin to the flywheel. Dynamic analysis and finite element modelling were carried out to determine the state of stress in the crankshaft. Finite element analysis was performed to obtain the variation of stress magnitude at critical locations. We know that, the performance of any automobile largely depends on its size and working in dynamic conditions. The design of the crankshaft considers the dynamic loading and the optimization can lead to a shaft diameter that satisfying the requirements of automobile specifications with cost and size effectiveness. The review of existing literature on crankshaft design and optimization is presented. The materials, manufacturing process, failure analysis, design consideration of the crankshaft are reviewed here.
