| description | The subject of research in the article is the process of vibratory movement of tangent structures in closed volumes (pipes). The purpose of this work is to investigate the mechanism of vibrational movement of tangent structures in closed volumes (pipes). The following tasks are solved in the article: to study the oscillating motion of a tangent structure consisting of a cantilever rod with a fixed end at the base, and by means of supports connected by dry friction with two parallel rough planes; the experimental method confirms the possibility of vibrational movement of the inner element of the tangent structure along the cylinder. The following methods are used: mathematical modeling and experimental study. The following results were obtained: a mathematical model of motion of a tangent structure is proposed, consisting of a cantilever rod with a fixed end, which by means of supports is connected by the force of dry friction with two parallel rough planes when applying a vibrating force perpendicular to the longitudinal axis of the structure; confirmed the possibility of vibration movement of the inner element of the tangent structure (cantileverly mounted rod in a cylindrical basis) along the outer element of the tangent structure (cylinder) when applying a vibrating force perpendicular to the longitudinal axis of the rod. Conclusions: 1) the effect of forced oscillations on tangent structures with structural asymmetry of the inner element of the tangent structure may cause the effect of vibrating movement of the inner element of the tangent structure relative to the outer element; 2) possible vibration movement of the inner element of the tangent structure (cantileverly mounted rod in a cylindrical basis) along the outer element of the tangent structure (cylinder) at an angle between the longitudinal axis of the inner element and the direction of external vibration force, which is equal to 900; 3) possible stopping of the inner element of the tangent structure, in the absence of the action of external vibrating force, in the place of the outer cylinder, in which the effect of the external vibrating force has stopped. |
