Description

Изобретение относитс  к измерению деформаций, а именно к способам закреплени  тензорезисторов на детап сх, и может быть использовано при испытани х объектов в услови х варьшиого нагруже-The invention relates to the measurement of deformations, and in particular to methods of fixing strain gauges on parts, and can be used for testing objects under varying loading conditions.

ВИЯ.VIA.

Известны способы закреплени  тензорезисторов на поверхност х датапей, заключающиес  в том, что поверхность деталей подготавливают, нанос т клей на деталь и тензорезистор, накладьгеают тензорезистор на поверхность детали, прижимают к ней. тензорезистор в течение определенного времени при опреде-ч пенной температуре ij.There are known methods for fixing the strain gauges on datapay surfaces, which consist in preparing the surface of the parts, applying glue to the part and the strain gauge, applying a strain gauge to the surface of the part, pressing it to it. strain gauge for a certain time at a certain foam temperature ij.

Однако необходимость длительного выдерживани  места соединени  под давлением и при определенной температуре не позвол ет оперативно замен ть тензореаисторы в полевых услови х в случае их повреждени  при транспортировке объекта к месту испытаний или же во врем  испытаний.However, the need to keep the junction under pressure and at a certain temperature for a long time does not allow for rapid replacement of the strain gauges under field conditions in the event of damage during transportation of the object to the test site or during tests.

Известен способ закреплени  тензорезисторов на объектах, заключающийс  Б том, что тензорезистор прижимают к поверхности объекта 2There is a method of fixing the strain gauges on objects, which consists in the fact that the strain gauge is pressed against the surface of the object 2

При такрм осуществлении закреплени  тензорезисторов сцепление с поверхностью объекта осуществл етс  за счет сил трени  благодар  силе нормального давлени , создаваемой зажимом. Однако использование зажимов не может обеспечить надежность закреплени  тензорезисторов и достоверность результатов измерени  в услови х взрывных нагрузок, так как зажим при взрывных нагрузках будет представл ть собой колеблющуюс  массу, способную оказать на температуру или объект неконтролируемые динамические воздействи , например, изменить силу прижати  или сместить тензорезистор , изменить нагрузки и т. п,When clamping resistors are attached, the adhesion to the object surface is achieved due to friction forces due to the force of the normal pressure created by the clip. However, the use of clamps cannot ensure reliable fixing of the strain gauges and the accuracy of the measurement results under conditions of explosive loads, since the clamp with explosive loads will be an oscillating mass that can exert uncontrolled dynamic effects on the temperature or object, for example, to change the pressing force or shift the strain gauge , change the load, etc.

Пелью изобретени   вл етс  повышение надежности закреплени  тензорезисторов на объектах различных габаритов при нагружении их взрывом.The invention is an increase in the reliability of fixing strain gages on objects of various dimensions when loaded with an explosion.
