WP 510 Torsion Testing Machine, 200 Nm, Motor Driven
Education / GUNT Hamburg / Engineering Mechanics and Machine Elements / Properties of Materials /
The unit is used for torsional testing of different materials to fracture. Test moment and angle of twist are measured. Bars of different length and diameter are used as specimens. The moment is applied using a reduction geared motor that provides four different drive speeds via the frequency converter. A strain gauge measuring shaft provides the moment as an electrical signal, the angle of twist is recorded by an optoelectronic angular encoder. Both values are displayed on a LC display. The moment is transmitted to the test bars using commercially available hex sockets. For adaptation to different length probes, the dolly can be slid. The base plate is reinforced against twisting with square sections. A transparent plastic cover provides protection against flying debris on fracture.
