Construction and Design
The Torsional Vibration System - Vibrano X - 10 is built on a frame made of anodized aluminum profiled structure, sized 1400mm x 400mm with a groove width of 10mm. The main unit consists of metal torsion bars made of corrosion-resistant stainless steel. With the aid of chucks, mass discs of varying inertia can be attached to the bars, allowing assembly of torsional vibrator systems with up to three masses.
Four ball bearing mounted bearing units with chucks can be positioned anywhere along the length of the shaft. Vibrations are induced on the system using a servo motorized exciter with a drive crank, offering excitation amplitudes of 1.4°, 1.6°, and 2.4°, controlled through the control unit. An adjustable oil damper is used to influence the vibrations.
Shaft encoders on the chucks provide the amplitude of vibration as an electrical signal. The control unit conditions these signals and makes them available for display on data acquisition software or on an oscilloscope, which is optional. This Torsional Vibration System uses four angle of rotation sensors of contact type, with a measuring range of 0 ~ 360°.
