In the drives of various machine units, clutches are widely used as a connecting element transmitting energy from one part of the machine to another. Among them, permanent clutches are prevailing, and they include elastic clutches with metal elements, such as cylindrical rods, cylindrical coil springs, tapes, spring holder packs and plate packs. The torsional rigidity is an important characteristic of clutches. Study results of the elastic non-linear clutch with a soft characteristic are presented. Elastic elements are plates exposed to buckling during compression. The study was performed numerically by the finite element method using the ANSYS R17.0 Academic software applied package. On the basis of the data obtained, analytical dependencies are proposed to determine the clutch torsional stiffness and to calculate the elastic elements strength. Description is provided of the tests carried out on the elastic elements to assess the analytical dependencies accuracy, which showed their suitability in practical calculation of strength and stiffness.
