Description
The bench top educational machine enables the students to study the torsion testing of varying material test specimen to failure. Rods of different materials, length and diameter are used as a specimens. Test torque and angle of twist and modulus of rigidity (on software) are measured.
For adjustment of different length specimens the measurement jig can be slide along the frame. Torque is applied
manually by hand wheel and worm gear.
The unit is used for torsional testing of different materials to fracture. Test torque and angle of twist are measured. Rods of different materials, length and diameter are used as specimens. For adaptation to different length rods, the dolly can be slide. The test rod holder is a commercially available socket. The base plate is reinforced against twisting with square sections.
The torque is applied using a reduction geared Mechanism. Two different drive velocities (both clockwise and counterclockwise) are realised. A strain gauge measuring shaft twist provides the torque as an electrical signal, the angle of twist is recorded by an incremental encoder. Both values are displayed digitally. The microprocessor-based measuring technique is well protected in the housing. All the advantages of software-supported experiments and evaluation are offered by the software and the microprocessor. The connection to a PC is made by USB (optional).
