Description

Изобретение относитс  к методам исследовани  прочностных свойств материалов, а именно к испытани м на прочность полых конструкций давлением.The invention relates to methods for investigating the strength properties of materials, namely, testing the strength of hollow structures by pressure.

Известен способ испытани  полой тонкостенной конструкции на прочность, заключающийс  в том, что конструкцию нагревают и одновременно нагружают давлением газа со стороны нагреваемой поверхности до разрушени .A known method for testing the strength of a hollow thin-walled structure is that the structure is heated and simultaneously loaded with gas pressure from the side of the heated surface before destruction.

Недостатком известного способа  вл етс  то, что он не позвол ет воспроизводить напр женное состо ние конструкции от нагрузок , возникающих при одностороннем обтекании ее стенки высокотемпературным потоком газа с неравномерным полем давлени .The disadvantage of the known method is that it does not allow reproducing the stress state of the structure from the loads arising from the one-sided flow around its wall by a high-temperature gas flow with an uneven pressure field.

Предложенный способ отличаетс  от известного тем, что на поверхности конструкции, обратной нагреваемой, размещают контактирующий с ней набор камер, в котором создают давление по заданной программе. Это приближает услови  испытани  к эксплуатационным .The proposed method differs from the well-known fact that a set of chambers in contact with it is placed on the surface of the inverse heated structure, which is pressurized according to a given program. This brings test conditions closer to operational ones.

Способ заключаетс  в следующем.The method is as follows.

Поверхность конструкции нагружают заданным посто нным давлением газа и одновременно со стороны этой же поверхности конструкцию нагревают. Б то же самое врем  в камерах, контактирующих с поверхностью, обратной нагреваемой, создаетс  давление, ооеспечивающее в каладой точке конструкции давление , равное заданному.The surface of the structure is loaded with a given constant gas pressure and at the same time from the side of the same surface the structure is heated. At the same time, in the chambers in contact with the surface that is inversely heated, a pressure is created that ensures a pressure at each point of the design equal to the specified one.
