Abstract

This paper introduces a new study to improve performance of the v6-engine crankshaft as V-type engine crankshaft has little consideration in literature. First, static analysis for v6-crankshaft is presented including geometric parameters, loading analysis and material selection. Secondly, finite element method is applied to analyze a model for v6-crankshaft with a fine element mesh. The boundary condition is formulated to simulate the proposed model. Then, solution for maximum equivalent stress, total deformation and safety factor is carried out. The solution indicates that fillet areas are the most critical sections with highest stress concentrations. Finally, parametric optimization technique is performed to detect the optimum values for fillet radii that produce minimum equivalent stress and minimum total deformation. The optimized model is compared with the original model and theoretical calculations. In the optimized model, maximum equivalent stress is reduced by 34.45% with an increase in mass by 0.02%. Geometric optimizing of v6-crankshaft design provides an effective methodology to improve its performance.
