Vibration Analysis

PERT'S philosophy of mechanical engineering training can be summed up in three words: visible and functional. PERT equipment clearly illustrates concepts and provides easy and workable experiments.

Torsional Vibration Apparatus

The model enables rotary vibration on torsion bars to be investigated.

The model consists of a wall mounted base frame made of aluminium. The carrier plate has a strong chuck with the aid of which the torsion bars can be clamped in position. In the same way the mass disc and the mass ring are clamped to the torsion bar using a chuck. The effective length is easy to adjust

Technical data:

• Test wires 1100mm, made of aluminium Diameter: Ø2, Ø3, Ø4, Ø5 and Ø6mm Mass disc: Ø160mm Mass ring: oØ160mm, iØ100mm
• Dimensions and weight l x w x h : 200 x 150 x 270 mm Weight approx. : 10 kg

List of experiments:

• Determination of the period of torsional vibration as a function of:
• The torsion wire length.
• The torsion wire diameter.
• The rotating mass and its form
