Abstract
With the modernization of the technology, significant emphasis has been given to weight reduction in the number of engine components. This change is predominantly governed by the introduction of composites and ceramics. The crankshaft is an important part of an IC engine that converts the reciprocating motion of the piston into rotary motion through the connecting rod. This paper is focused on the weight optimization of the crankshaft by analyzing it for different stresses and dynamics loads using different materials viz. AISI 4340, Al B4C, AISI 4330M, 42-CrMo-4, AISI 6061-T6, and Aluminum alloy. Computational study of the different candidate materials for the crankshaft is done using an inline 4-cylinder diesel engine. A standard 3D model of the crankshaft is made using DS Solid works 2013 software and the computational analysis is being carried out using Ansys Workbench. The study focuses on decreasing the weight of the crankshaft while maintaining not much alteration to induced stresses and deformation, therefore increasing the efficiency and torque output of the engine. Analysis of each candidate material is done for maximum pressure and maximum torque conditions simultaneously and the results are compared and evaluated to find the suitable material with less density and good strength to weight ratio.
