Abstract
Изобретение относитс к области испытани материалов на ударное воздействие, а именно к устройствам дл разрушени мембран в одноимпульсных ударных трубах . Цель - расширение экспериментальных возможностей путем увеличени скорости ударной волны при создании ею плоского фронта за счет обеспечени безостаточного разрыва мембраны. Устройство дл разрыва мембраны водноимпульс- иой ударной трубе содержит полый корпус 1, между фланцем 5 которого и фланцем патрубка 3 защемлена мембрана 4. Нож 7 дл разрыва мембраны состоит из секторов, шарнирно закрепленных на конце полого поршн привода 12, подпружиненного упругим элементом 8. Шариковый замок выполнен в виде стопора 9, который, попада в кольцевую проточку на поршне 13, который в свою очередь двигаетс под действи- ем давлени в камере 15, освобождает полый поршень привода 12 и нож 7 врезает-1 с в мембрану 4. 4 ил.jThe invention relates to the field of impact testing of materials, in particular to devices for breaking membranes in single-pulse shock tubes. The goal is to expand experimental capabilities by increasing the speed of the shock wave while creating a flat front by providing a non-permanent rupture of the membrane. The device for rupture of the membrane of the water-pulse shock tube comprises a hollow body 1, between the flange 5 of which and the flange of the nozzle 3 the membrane 4 is clamped. The knife 7 for rupture of the membrane consists of sectors pivotally mounted on the end of the hollow piston of the actuator 12, spring-loaded with an elastic element 8. Ball the lock is made in the form of a stopper 9, which, falling into the annular groove on the piston 13, which in turn moves under the action of pressure in the chamber 15, releases the hollow piston of the actuator 12 and the knife 7 cuts -1 s into the membrane 4. 4 il. j
