Abstract

Изобретение относится к космической технике и, в частности, к способу и технологии изготовления крупногабаритных антенн с трансформируемым крупногабаритным рефлектором. Предлагаемый способ включает предварительный расчет конечно-элементная модель рефлектора, сборку фрагментов формообразующей структуры на полу без использования технологического шаблона с учетом напряженно-деформированного состояния формообразующей структуры и силового каркаса рефлектора и настройку рабочей поверхности рефлектора без использования технологического приспособления (шаблона) для сборки и настройки рефлектора. Технический результат изобретения состоит в обеспечении геометрических характеристик рабочей поверхности рефлектора и усилий непосредственно сразу после сборки без регулировки в составе рефлектора. Предлагаемый способ изготовления позволит обеспечить заданную форму поверхности с относительно небольшими отклонениями, а также равномерность усилий натяжения шнуров формообразующей структуры уже на этапе начальной сборки за счет учета влияния внутренних напряжений без использования громоздкого, трудоемкого технологического оборудования, а также позволит сократить время и затраты на изготовление рефлектора.The invention relates to space technology and, in particular, to a method and technology for manufacturing large-sized antennas with a convertible large-sized reflector. The proposed method includes a preliminary calculation of the finite element model of the reflector, the assembly of fragments of the forming structure on the floor without using a technological pattern, taking into account the stress-strain state of the forming structure and the power frame of the reflector and setting the working surface of the reflector without using a technological device (template) to assemble and configure the reflector . The technical result of the invention is to provide the geometric characteristics of the working surface of the reflector and effort immediately immediately after assembly without adjustment in the composition of the reflector. The proposed method of manufacturing will allow to provide a predetermined shape of the surface with relatively small deviations, as well as the evenness of the tension of the cords of the forming structure already at the initial assembly stage by taking into account the effect of internal stresses without using cumbersome, labor-intensive manufacturing equipment, and will also reduce the time and cost of manufacturing a reflector .
