Stress analysis of a connecting shackle
Bodo, Ondrej ; Hrstka, Miroslav (referee) ; Vaverka, Jiří (advisor)
The bachelor thesis deals with the stress analysis of a selected real connecting shackle using an analytical model based on the beam theory. In the first part, the basic classification of the used types of shackles according to their shape, removable pin or used materials is presented. The following part briefly presents the mechanical theory of linear elastic bars and beams complemented by the theory of curved beams, on the basis of which two analytical models differing in the use of symmetry are developed in the practical part. In both cases of the analytical models, the results with or without the use of the theory of curved beams are also compared, thus proving its applicability. The analytical section also includes an analysis of one ear of the shackle. Finally, the results obtained by the analytical solution are verified by computational modelling using the finite element method in ANSYS Workbench 2023 R2 software, where, in addition to the verification of the model calculated in the analytical solution, a more realistically distributed loading of the shackle is also considered, together with the verification of the maximum stresses of the ear using 3D solid elements.
