Description

сигналов датчика 10 и задатчика 12, что соответствует достижению образцом 6 заданной деформации. После этого привод 2 нагружени  отключаетс  и т га активного захвата 8 остававливаетс . Образец 6 продолжает удлин тьс  за счет податливости цепи нагружени . При этом по вл етс  сигнал, который преобразовываетс  в регул торе 13 н через усилитель 14 вызывает подачу питани  на сре дство 9 изменени  температуры стержн  7. Нагрев стержн  7 сопровождаетс  его линейным расширением в сторону, противоположную приращению деформации образца 6 относительна заданного уровн , и образец 6 возвращаетс  к заданному уровню деформации .the signals of the sensor 10 and the setting device 12, which corresponds to the achievement of the specified deformation by the sample 6. After that, the loading mechanism 2 is switched off and the load of the active gripper 8 is stopped. Sample 6 continues to lengthen due to the flexibility of the loading circuit. In this case, a signal appears that is converted in the 13n controller through the amplifier 14 causes the supply of the medium 9 to the temperature change of the rod 7. The heating of the rod 7 is accompanied by its linear expansion in the direction opposite to the increment of the deformation of the sample 6 relative to the specified level, and the sample 6 returns to a predetermined strain level.

Изобретение позвол ет повысить точность испытани  на релаксацию напр жеНИИ за счет обеспечени  безлюфтового регулировани  дефорМ1ации образца и поддержани  ее на заданном уровне.The invention makes it possible to increase the accuracy of testing the relaxation of the INR due to the provision of backlash-free regulation of the deformation of the sample and maintaining it at a predetermined level.
