Abstract
1. Способ изготовления оболочек отрицательной кривизны, включающий укладку и закрепление термоусадочного термопласта в пространственном каркасе и совместного нагрева каркаса с термопластом, отличающийся тем, что трубчатый элемент термоусадочного термопласта сначала нагревается с одного конца до высокоэластического состояния и при этом зажимает верхнее кольцо каркаса, затем нагревается до высокоэластического состояния с другого конца, зажимая в себе нижнее кольцо, а затем с зажатыми обоими кольцами, скрепленными разборным сердечником, вся система вновь нагревается с 50°С только до начала высокоэластического состояния средней части будущей оболочки отрицательной кривизны. ! 2. Способ по п.1, отличающийся тем, что каркас разбирается путем вывинчивания резьбовой нарезки стержней с сердечника и колец (верхнего и нижнего) и готовая оболочка остается с двумя кольцами (верхним и нижним). ! 3. Способ по п.1, отличающийся тем, что оболочка отрицательной кривизны с двумя зажатыми кольцами подвергается внутреннему давлению (пневмо - или - гидро) для статических механических испытаний.1. A method of manufacturing shells of negative curvature, including laying and fixing a heat-shrinkable thermoplastic in a spatial frame and co-heating the frame with thermoplastic, characterized in that the tubular element of the heat-shrinkable thermoplastic is first heated from one end to a highly elastic state and at the same time clamps the upper ring of the frame, then heats up to a highly elastic state from the other end, clamping the lower ring in itself, and then with both rings clamped together by a collapsible core m, the whole system is heated again to 50 ° C just prior to the highly elastic state the middle part of the future shell of negative curvature. ! 2. The method according to claim 1, characterized in that the frame is disassembled by unscrewing the threaded rods from the core and rings (upper and lower) and the finished shell remains with two rings (upper and lower). ! 3. The method according to claim 1, characterized in that the shell of negative curvature with two clamped rings is subjected to internal pressure (pneumo - or - hydro) for static mechanical tests.
