Abstract

The paper presents the analysis of the elastic coupling with flexible elements, taking into
consideration the mechanical strength criterion in conditions of normal loading or torsion overload, with
and without misalignment, using finite element analysis, responding to multiple demands that are required
in coupling structure. There are presented the basic principles for applying the finite elements method: the
study of convergence at different mesh sizes, the loading scheme and boundary conditions for the flexible
element. Also, the paper presents several simulations to prove the behaviour and functionality of the
coupling for different operational scenarios: mechanical stress, buckling stability and modal analysis.
