Construction and Design
The Free & Damped Torsional Vibration Apparatus – Vibrano X – 07 is built around three torsion bars made of stainless steel and two mass discs. The components are accurately placed in slots of the frame on the vibration system. An adjustable ball bearing chuck holds the torsion bars in place, with a diameter range of D=0.5…8.0mm. An open oil filled damper is fitted to reduce vibration amplitude. An exciter unit is included to generate forced vibration for testing. This Free & Damped Torsional Vibration Apparatus is designed as a supplementary experiment to the universal vibration system.
