Digital Torsion Testing Machine
Digital Torsion Testing Machine has a maximum torque rating of 600 Nm and a speed of rotation that can be varied between 0.1 and 250 radians/min. The headstock is electro-mechanically operated.
The integrated analogue/digital interface and software are used for control, data acquisition and analysis using an IBM compatible PC.
Specimens and components of various sizes and materials can be used. Tests may be carried out at fixed or variable speed, in continuous or alternate mode as a function of torque, speed or acceleration.
Teaching objectives
The torsion test machine allows a wide range of tests and experiments, including :
- Torsion in a solid rod, transmission components (cable, clutch etc).
- Fatigue testing in torsion up to 1 Hz
Technical specifications
