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.
Software
Software Vibrano X - 07 (optional)
DAQ software specially designed in National Instrument™, LabVIEW™ environment to measure and calculate the results of the apparatus. The software is optional. While using the software, a set of electrical vibration sensors with clamping set is included. The software can be run with any Windows™ environment.
