Structural and modal analysis of crankcase of single cylinder diesel engine

Abstract

Among the most critical components, crankcase the housing for the crankshaft is used for effective and precise working of the internal combustion engine. The main aim of this work is to analyze the structural and modal parameters of the crankcase of diesel engine of existing and modified model. Solid model of the crankcase is generated using the commercially available software packages, as per the dimensional details of existing crankcase. Static and vibrational analysis of the crankcase is carried out using commercially available software packages for the boundary conditions in accordance with engine specifications and mounting conditions. The modified model of the crankcase is also modeled, analyzed and compared with the existing model of the crankcase. The modified model is prepared for the experimentation using the fast fourier transformer (FFT) analyzer. Simulation results show that the modified model of the crankcase demonstrates the reduced stresses (by 10%) and deformation by (40%) with the existing model also absorb more vibrations. © 2022, The Author(s), under exclusive licence to Springer-Verlag France SAS, part of Springer Nature.
