Изобретение относитс к испыта и м на прочность полых изделий.This invention relates to the testing of the strength of hollow articles.
Наиболее близким по. технической сущности к предлагаемому вл етс устройство дл испытани на прочность полых тонкостенных изделий, содержащее корпус, размещенные в нем нагревательные элементы, набор камер, устанавливаемых на поверхности конструкции , обратной нагреваемой, и системы подачи и управлени давлением i 3The closest to. The technical essence of the present invention is a device for testing the strength of hollow-walled thin-walled products, comprising a housing, heating elements housed therein, a set of chambers mounted on the surface of a structure that is reverse heated, and a pressure supply and control system i 3
Недостаток данного устройства, заключаетс в ненадежности испытаний, св занной со сложностью регулировани давлени по заданной программе.The disadvantage of this device lies in the unreliability of tests associated with the difficulty of controlling the pressure according to a given program.
Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.
Указанна цель достигаетс тек, что камеры сообщены друг с другом через калиброванные отверсти , площадь KOTOpbtx выбрана из расчета обеспечени давлений по заданной программе , одна из крайних камер сообщенаThis goal was achieved, that the chambers communicated with each other through calibrated holes, the KOTOpbtx area was chosen on the basis of ensuring the pressures according to a given program, one of the extreme chambers communicated
С системой управлени давлением, а друга - с полостью корпуса.With a pressure control system, and a friend with a body cavity.
На чертеже представлена схема устройства,The drawing shows a diagram of the device
Устройство содержит корпус 1, в котором установлена испытуема конструкци 2 и нагревательные элементы 3, камеры 4, образованные, например , поверхност ми конструкции 2 и цилиндра 5, на котором закреплены The device comprises a housing 1, in which the tested structure 2 is installed and the heating elements 3, chambers 4 formed, for example, by the surfaces of the structure 2 and the cylinder 5 on which are fixed
10 кольцевые диа фагмы 6 с эластичными уплотнительными элементами 7. Камеры 4 сообщены друг с другом калиброванными отверсти ми 8, площадь которых выбрана из расчета обеспечени давts лений по заданной программе, система 9 управлени давлением и система 10 подачи давлени .10 annular diaphagms 6 with elastic sealing elements 7. The chambers 4 communicate with each other by calibrated holes 8, the area of which is chosen on the basis of providing pressure for a given program, the pressure control system 9 and the pressure supply system 10.
Устройство работает следующим образом .The device works as follows.
2020
В корпус 1 и в камеры 4 синхронно подаетс давление,.равное максимальному заданному давлению. Конструкци 2 нагреваетс нагревательнымиPressure is applied synchronously to housing 1 and to chambers 4 equal to the maximum predetermined pressure. Construction 2 is heated by heating
элементами 3, а давление по заданной программе регулируетс системой 9 управлени давлением. При перетекании газа по камерам А через калиброванные отверсти 8 реализуетс заданное распределение давлений по длине конструкции 2.elements 3, and the pressure according to a predetermined program is regulated by pressure control system 9. When gas flows through the chambers A through the calibrated orifices 8, a predetermined pressure distribution along the length of the structure 2 is realized.
IlpejwiaraeMoe устройство позвол ет проводить испытани , использу в системе управлени давлением лишь один регул тор, что позвол ет повысить надежность испытанийtIlpejwiaraeMoe device allows to carry out tests using only one regulator in the pressure control system, which allows to increase the reliability of the tests
