1.Product introduction
Tensile and torsion testing machines are mainly used to test the dynamic and static mechanical properties of tiny metals, non-metallic materials and components, elastomers, and shock absorbers.Can realize sine wave, triangle wave, square wave and other waveforms.Equipped with different fixtures, mechanical tests such as tension, compression, tension and compression, and tension and torsion can be performed.
The testing machine consists of an electrical controller, an electric cylinder, a load sensor, a displacement sensor, a torsion drive device, test software and a computer to form a closed-loop control system to achieve automatic and precise control of the test process, and automatically measure test force, torque, displacement, deformation and other test parameters.The test process is all under computer control, making it an ideal and cost-effective test system for scientific research institutes, metallurgical construction, national defense industry, universities, machinery manufacturing, transportation and other industries.
The test mode can support: uniaxial tension, uniaxial compression, tension torsion, compression torsion, and torsion fatigue tests.It can support customized test plans and draw force-displacement and stress-strain curves in real time.Supports automatic sensor calibration and real-time parameter adjustment.
