1 Main function 1) it mainly used in torsion test and research under room temperature with various materials. 2) It tests and researches with cylinder and tubular sample for continuous torque loading, torque grading loading, torque, Max. Torque, torsion strength, yield strength, upper yield strength, lower yield strength, nominal non-proportional torsion strength, Max. Non-proportional shear, shear modulus and other properties. 3) It tests and researches torsion fatigue and fatigue life property with metal and non-mental. 4) it tests bonding layer between metals and metal and nonmetals, bolts, valves, pipe fittings, wrenches, soft materials, composite materials, wires with increasing gripper.
2 Important characteristics 1) horizontal type, high rigidity and stability loading frame, size of loading frame is able custom made. 2) Auto kept loading, stress and strain control, cycling control, self-editing control and multiple control mode. 3) High precision and symmetric torsion sensor, wide linearity, well stability, which guarantee precision of torque. 4) High speed, low vibration, free maintaining, mute type of current servo motor actuator system. 5) Inner placed Ethernet joint, emergency stopping and loading function, flexible operation and switching. 6) Circuit board adopts photo-electricity isolation designing with high anti-interference. 7) With variety of high quality gripper, environmental system and torsion angel meter. 8) Wide test speed: 0°--720°/min(set freely) 9) Total digital close loop, multiple channel and function, easily operating (shenli-Test) software. There are variety of tests method, standard in data base, test data is stored inquired and transferred. ① Test procedure is auto controlled, torque, stress, deformation, torque angle totally controlled and displayed, whole keyboard inputting and intelligent control mode system, control mode set freely without impact, switching smoothly, loading and unloading steadily. ② Flexible Excel and Word report with normal and self-editing comfort, multiple items ordered and output. ③ Reappearing test completes data re-analyzing, overlapping,and comparing multiple curves. ④ Test curves is zoom in and out with any coordinate axis, multiple curves is displayed at the same time, such as torque-time, torque- angle and angle-time curves. Coordinate axis is set freely. ⑤ Modulus, opening program satisfies individual requirement with hinting and guiding function. ⑥ Auto returning after test completed with intelligent, high efficient and convenient. ⑦ Auto calculating modulus G, nominal non-proportional torsion stress τp , upper yield strength τeH , lower yield strength τeL, torsion strength τm and so on. ⑧ Auto-measuring torque and angle and displaying test curves with value of torque, torque angle, and torsion speed. 10) multiple protective function: over loading, current, voltage, sample breaking safety and emergency stop protection.
