Investigation of displacements in semi-rigid couplings with two corrugations

Abstract

The methodology for determining displacements in a semi-rigid coupling with a single corrugation has been described earlier. In practice, two or three corrugations are often used in order to increase elasticity. Increasing the number of corrugations changes the deformation conditions and requires separate consideration. The purpose of this paper is to investigate the effect of corrugations on the displacements of the entire coupling and its individual elements. The main value determining the elasticity of the coupling is the angle of rotation α (Fig. 1). It depends on the value of the bending moment M, the size and material of the corrugation. In the future, we take the angle a, as well as the dimensions of the coupling, as given.The stated methodology for determining displacements in couplings with two corrugations can be extended to couplings with three corrugations.
