摘要：
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. Specific features of mathematical models of cable tethering systems of telecontrolled unmanned submarines based on discrete and continuous models are considered. A number of specific features of their operation determines the expediency and sometimes the necessity 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 calculations, the earlier assumptions about the movement of the cable along its initial configuration of the towing line for the variable length of the cable were precised. It was found that this assumption is correct only for the initial transition section. It was also ascertained 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 promoting the cable system breakage and looping during towing. © 2020 by Begell House Inc.
