TORSIONAL VIBRATION APPARATUS

A bench top unit for studying torsion and torsional vibration, constructed around a profiled aluminium base with levelling feet and four vertical chuck pillars. Each pillar contains a central shaft running in precision bearings with a chuck that grips a torsion specimen. Each chuck also carries a large disc of varying mass and inertia, enabling assembly of a torsion specimen with up to three masses.

A fifth chuck rigidly clamps the specimen end to achieve a fixed end condition. Learn about TORSIONAL VIBRATION APPARATUS specifications for optimal educational outcomes.. A manual torsion arrangement allows a known angular twist to be applied using a cord, load hanger and weights set, enabling calculation of the modulus of rigidity. Oscillation sensors are mounted integrally with each mass pillar and feed signals to a digital oscilloscope for vibration analysis.
