The Torsion machines are used to determine the compartment of materials subjected to rotational loads. The resulting data are used to represent a load-deformation diagram from which a number of material properties can be obtained, such as:
- Shear yield strength
- Maximum resistance
- Limit proportional to the cut-off
- Modulus of rigidity
- Resilience
- Toughness
- Types of failures.
These tests are used on materials such as transmission shafts, screws, torsion springs and crankshafts. By means of them, we can know the resistance when these materials are subjected to forces. In addition, we could also know their torsion angle and the force that the material supports before breaking.
Torque machines have two parts:
- Load unit: Place where the piece to be tested is held.
- Control unit: All test characteristics such as speed or torque increments are controlled here.
Some of the most important tests that we can do with a torsion machine are:
- Torsion test: A bar is held at one end and a torque is applied at the opposite end.
- Bauschinger effect: With this test we can find out the stress distribution after the material undergoes deformation.
- Residual stresses: This test is used to measure the stresses that arise from the change in volume of the material.
Generally, torque machines are common in materials testing laboratories, engineering, industrial, civil, electrical or mechanical schools.
At Servosis we have two types of twisting machines:
- Rotational Flexion: This machine has been designed to perform tests with bars of any material subjected to simultaneous turning and bending stresses.
- MT Series: This type of machine is designed to perform torsion tests for all types of materials, being especially useful for testing wires. This machine allows testing specimens with pre-stressing in the axial direction of the load by means of a pneumatic cylinder.
At ServosisWe offer the best machinery to perform this type of tests. For more information, please contact us. our catalog and if you have any questions or suggestions you can contact us at contact form.
