“…To assess the deflections and reaction forces distribution at the contact between vee-block support heads with the main journals, a finite element model [ 23 , 24 ] of the crankshaft was established—Midas 2019 (Midas Information Technology Co. Ltd., Seongnam, Korea) [ 25 , 26 ]. The geometrical model of the analyzed shaft was discretized using four-sided solid elements (CTETRA) with three translational degrees of freedom in each node.…”

This article presents a multi-criteria analysis of the errors that may occur while measuring the geometric deviations of crankshafts that require multi-point support. The analysis included in the paper confirmed that the currently used conventional support method—in which the journals of large crankshafts rest on a set of fixed rigid vee-blocks—significantly limits the detectability of their geometric deviations, especially those of the main journal axes’ positions. Insights for performing practical measurements, which will improve measurement procedures and increase measurement accuracy, are provided. The results are presented both graphically and as discrete amplitude spectra to make a visual, qualitative comparison, which is complemented by a quantitative assessment based on correlation analysis.

“…Jiao et al [23] did the modal and fatigue analysis of a crankshaft in addition to the physical and chemical scrutiny and introduced the main cause of crankshaft failure as fatigue resulted from overload. Kubet et al [24] provided the static, modal, and harmonic analyses. The latter is used to determine the harmful frequencies of vibrations, having the possibility to break the structure.…”

“…In our analysis, steel is chosen for the crankshaft, and aluminum is used for piston, connecting rod, and pin [28] . The material choice of the components is addressed in several research works [24,29] . Generally, accurate material behavior depends on the strain rate, temperature, material texture, and so on.…”

In this work, a typical vehicle engine is modeled within PTC-Creo software, and its thermal, mechanical, and thermo-mechanical performance are evaluated. This is followed by the vibrational, fatigue, and buckling analysis of the assembly of components, which are the predominant failure causes. The results show that the least temperature gradient occurs in the center of the pin, which connects the piston to the connecting rod, the maximum displacement is seen just below the piston head, and the thermo-mechanical failure is caused mostly (about 85%) by the mechanical load rather than the thermal one. Also, in fatigue analysis, the minimum and maximum values for the safety factor are 0.63 and 5, respectively. The results can prevent the reoccurrence of similar failures and help the enhancement of the components’ design and manufacturing process.
