measure the test moment by means of strain gauge
| Code | WP510 |
Description:
- The torsion test is a destructive testing method that studies the plastic behaviour of materials.
- In practice, components that are twisted in their application (e.g., screws, shafts, axles, wires and springs) are studied with this test method.
- The WP 510experimental unit allow torsion tests in which specimens are subjected to load until they fracture.
- The clean layout and simple operation mean the experimental sequence can be observed in all details and phases.
- The power of the experimental unit allows tests to be performed on an industrial scale.
- In the experiment, metallic specimens are twisted until they are destroyed by typical shear fracture.
- The twisting moment is applied from a high-ratio reduction gear motor.
- A frequency converter offers four different drive velocities in forward and reverse rotation.
- The base plate is torsionally reinforced.
- A transparent protective cover protects against flying fragments.
- Specimens of different materials and different lengths are included in the scope of delivery.
- The measuring device can be moved on the rigid frame to adapt to different specimen lengths.
- The effective twisting moment (test moment) is measured by means of a moment-measuring shaft fitted with strain gauges and can be read directly on a display.
- The twisting angle is recorded by an incremental encoder and can also be read.
- The microprocessor-based instrumentation is well protected in the housing.
- The GUNTsoftware, together with the microprocessor, provides all the advantages of using software to help conduct and analyse the experiments.
- The unit is connected to the PC via USB.
