Description

ное в виде сопла 5 со сменной шайбой 6 в критическом сечении, диаметр которого меньше диаметра волновода 3. Испытуемый объект 7 закреплен в приспособлении 8 перед соплом 5.in the form of a nozzle 5 with a replaceable washer 6 in the critical section, the diameter of which is less than the diameter of the waveguide 3. The test object 7 is fixed in the device 8 in front of the nozzle 5.

При взрыве зар да 2 в камере 1 формируетс  ударна  волна, котора  проходит по волноводу 3 до сопла 5. Здесь часть волны проходит через критическое сечение и воздействует на объект 7, а часть отражаетс  от стенки 9 и идет по волноводу 3 обратно. Затем происходит повторное отражение от стенки 10, и волна снова идет к соплу 5. Этот процесс повтор етс  до полного затухани  волны в волноводе 3. На объект 7 при этом действует последовательность ударных волн. Замена шайбы 6 измен ет услови  истечени  волны  з сопла 5, причем мен ютс  также параметры импульсов давлени , воздействуюш;их на объект 7. Изменение длины волновода 3 при смене отсека 4 приводит к изменению пути, проходимого волной между двум  последовательными отражени ми, и, следовательно, интервала времени между двум  последовательными импульсами нагрузки .With the explosion of charge 2 in chamber 1, a shock wave is formed, which passes through waveguide 3 to nozzle 5. Here part of the wave passes through the critical section and acts on object 7, and part reflects from wall 9 and goes through waveguide 3 back. Then, a repeated reflection from wall 10 occurs, and the wave again goes to nozzle 5. This process repeats until the wave in waveguide 3 is completely attenuated. Object 7 is affected by a sequence of shock waves. Replacing the washer 6 changes the conditions for the outflow of the wave from the nozzle 5, and the parameters of the pressure pulses that affect them are also changed; hence, the time interval between two consecutive load pulses.

Достигаемое изобретением упрощение конструкции и уменьшение габаритов стенда позвол ет достичь его удешевлени  и улучшить эксплуатационные качества.The simplification of the construction achieved by the invention and the reduction of the dimensions of the stand make it cheaper and more efficient.
