Comparative Study of the Life Prediction and Failure Analysis of Metal Powder (Vanadium-V) Coated on Crankshaft

Abstract

The crankshaft plays a crucial role in the efficient operation of internal combustion engines, converting piston reciprocating motion into rotary motion. This study aims at the life prediction and failure analysis of metal powder (Vanadium-V) coated on crankshaft using numerical method. It was modelled with SOLIDWORDS version 2019 and imported to ANSYS 2020 RI environment for static structural analysis. Numerical results of total deformations obtained from ANSYS are shown with the minimum value and maximum for propose material 7.3172e-5 and 0.00065855 respectively, and for the existing material value having 0.00014795 and 0.0013316 as well. Maximum and minimum values are 0.018841 and 2.9158e-7 in crankshaft equivalent elastic strain distributions in the existing material respectively. Results also show that maximum equivalent elastic strain is observed in propose with 0.097538 and minimum 3.1017e-7. The maximum value is 1.3933e9 and minimum value is 26418 of the stress found around the crankshaft of the propose and is stretched where there is concentration of pressure. The maximum stress intensity is observed in existing material with 1.5139e9 with minimum value of 30833. Results reveal significant improvements in total deformations, elastic strain distributions, and stress values for the proposed vanadium-coated material compared to the existing one. Despite a mere 0.0003mm thickness, the vanadium coating offers cost-effectiveness, better performance with cheaper lubricants, reduced friction, and enhanced dimensional tolerance at higher pressures. Results therefore proposed vanadium incorporated to inhibit grain growth to enhance strength and toughness of hardened steel.
