Problems of Control and Informatics| Summary: | Dynamics problems of geometrically nonlinear distributed mechanical systems in space, air, and water environments with variable dimensions are among the least studied problems of mechanics. The peculiarities of mathematical models of cable tethering systems of telecontrolled unmanned submarines based on discrete and continuous models are considered. A number of features of their operation determines the purposefulness, and sometimes the need, of a purposeful change in cable length. In such cases, the cable is not only a component of the overall dynamic tethering system, but it acts as an independent controlled object. As a result of the calculations, the earlier assumptions about the movement of the cable along its initial configuration were changed as the length of the cable changed. It has been found out that this assumption is only true for the initial transition participant. It is also established that at a given tachogram in the configuration of the towed line, there is a point of inflection, which shifts from top to bottom when lifting it. This can be an additional factor in the looping, contributing to the breakage of the cable system during towing. |
