Study of elastic line of semi-rigid coupling

Abstract

Increasing the elasticity of a coupling sleeve is usually achieved by installing one or more corrugations. A schematic representation of such a corrugation in deformed and undeformed states is shown in Fig. 1. (see article). The main value that determines the elasticity of the sleeve during bending is the rotation angle a. It depends on the magnitude of the bending moment, the dimensions and material of the corrugation. There are various theoretical and experimental methods for determining the value of a, which we will not dwell on - we will take the angle a, as well as the dimensions of the sleeve, as specified. The task is to determine the effect of the corrugation on the movements of the entire sleeve and its individual elements. These movements depend not only on the characteristics of the corrugation, but to a large extent on the position occupied by the corrugation on the sleeve and the dimensions of the sleeve itself.
