It is mainly used for torsion test of various materials such as metal and non-metal, which can realize torque and torsion angle control. The torsion test of parts and components can also be carried out by adding corresponding accessories. Under the computer control mode, equipped with a small angle measuring device can accurately obtain test data such as torsional elastic modulus (shear modulus G) and non-proportional stress (TP). 。
1. The testing machine is manufactured according to the standard of JB/T 9370-1999 "Technical Conditions for Torsion Testing Machines".
2. The testing machine is in accordance with GB/T10128-1998 "Metal room temperature torsion test method", GJB715.13 "Pre-tightening test method for installation of shaped fasteners", MIL-STD-1312, Test16 "Pre-tightening test method" and other standards Conduct experiments to provide data.
3. The testing machine can also provide data for testing according to European standards such as EN-14399-1:2005, EN-14399-3～6:2006 and ISO 898-1:1999.
1. An independent electronic measurement and control system can also adopt computer control, collection, analysis and processing of test data. The test data and curves are displayed dynamically along with the test process. The test data is automatically processed and displayed by a microcomputer. It draws torque-torsion angle and torque-time curves, connects to a printer and prints out test reports conforming to national standards such as test date, number, material, and torsion strength. Automatic tracking measurement of torsion angle, loading speed indication and peak value hold functions;
2. The open data connection interface can realize closed-loop control of torque, rotation angle, torsion angle, etc.; it can be controlled in a multi-step manner, and can realize no impact conversion between the three methods during the test, and has the function of maintaining load.
3. Using high-precision torque sensor, the resolution can reach 300,000 yards of full scale;
4. With overload and over-travel protection functions;
5. It can be loaded forward and backward, and draw the torsion hysteresis curve;
6. Using cycloid pinwheel reducer, the power transmission system is stable and reliable;
7. There is a torque fine-tuning handwheel, which can adjust the initial torque to zero;
8. Freely movable workbench, suitable for various lengths of samples;
9. Equipped with a mainstream brand commercial computer as the control machine to set test parameters, control working status, data acquisition, processing and analysis, display and print test results, etc.;
10. The torsion testing machine software package is pre-installed under the Windows operating system, which can be tested according to national standards or standards provided by users;
