micro-computer control electro-hydraulic servo universal tester( testing machine)

have been researched into, developed according to GB/T228-2002"Metal Material Room Temperature Tensile Testing Method".It is of wide use. Itcan implement the experimentations such as the tensile, compression, bending, cuttingetc.to the metal, nonmetallic composite materials. It adopts the four verticalcolumns framework structure. It is of the more stable construction and themore guaranteed rigidity. It utilizes the hydraulic chuck sample automatic clamping.It employs the high precision pressure-operated sensor to measure the hydraulicforce. It is of the high measuring accuracy and the wider range. It uses thehigh accuracy motion transducer. It adopts PCI wire control mode. It utilizesWindows XP operation system. It can be allocated with the touch screen which ismore beneficial for the operation and control modes such as the constant rate forcecontrol, constant rate stress control, constant rate deformation control, constantrate stroke control, low cycle fatigue control, consumer self-programmingcontrol etc. It can draw the multiple experimental curves such as the force-deformation,force-shift, stress-strain, force-time and so forth. It can partiallythe experimental curve and hold the additive comparison to the multi-curves. Itcan automatically seek the multiple technical parameters such as elastic moduleE, upper yield strength ReH, lower yield strength REL, stipulated non-proportionalelongation intensity Rr, tensile strength Rm,stipulated total elongation intensityRt,yield point percentage elongation etc. It can also print the complete experimentalreport and curve. It comprehensively conforms with GB/T228-2002 requirements
