Stresses and deformations in overlapped diesel engine crankshafts, Part 2: Evaluation of results

摘要: AbstractThe extensive results presented in Part 1 (in the previous issue*) have been supplemented and analysed further. A large number of cross-sections which could be reasonably used to calculate nominal stresses has listed evaluated.An inclined (flat, rectangular) section through web is shown best due torsion, pure radial bending crankpin forces; its width h (see Fig. 1), length shortest line joining journal fillets plane symmetry. Stress concentration factors based on these show only modest scatter from single curves for torsion bending.Predictions using most commonly method underestimate shear overestimate stresses.
