Description
Машина работает следующим образом. Испытуемый образец 25 устанавливаетс в захваты 8 и 14, дл чего траверса 5 перемещаетс в положение, соответствующее размерам, образца, за счет вращени колонн 2-4.The machine works as follows. The test specimen 25 is installed in the grippers 8 and 14, for which the crosspiece 5 is moved to a position corresponding to the dimensions of the sample, due to the rotation of the columns 2-4.
При испытании в полости камер подаетс давление от соответствующих гидроцилиндров . В случае испытани на сжатие давление подаетс в полости верхних камер, на раст жение - в полости нижних камер. Три датчика 2224 деформации, наклеенные на боковые поверхности образца напротив каждой иэ камер, регистрируют деформацию. Пр по влении эксцентриситета возникает сигнал рассоглас эвани ,и блок 21 управлени вырабатывает соответствующую команду, котора приводит к выравниванию показаний датчиков, повыша или понижа давлени в соответствующих полост х камер и тем самым обеспечива соосное приложение нагрузки к образцу.When tested in the cavity of the chambers, pressure is applied from the respective hydraulic cylinders. In the case of a compression test, pressure is applied in the cavities of the upper chambers, and in tension, in the cavities of the lower chambers. Three strain gauges 2224 glued to the side surfaces of the specimen opposite each of the chambers register the strain. When an eccentricity occurs, an evasive signal arises, and the control unit 21 generates the appropriate command, which aligns the sensor readings, raising or lowering the pressure in the respective chamber cavities and thereby ensuring coaxial application of the load to the sample.
При внецентренном испытании обеспечиваетс контроль посто нства изгибающего момента (то-есть посто нства разницы в показани х тенэодатчиков ) или изменени его по определенной программе.In the case of an off-center test, the constancy of the bending moment (i.e., the constancy of the difference in the readout of the temperature sensors) or its change according to a specific program is monitored.
