Construction and Design
The Free and Damped Torsional Vibration Apparatus ProDynami - 1314 includes three torsion bars made of stainless steel, with diameters of 3mm, 5mm, and 6mm, each 800mm in length. Two weight discs are provided: a large disc of D=228mm at approximately 4.8kg, and a small disc of D=150mm at approximately 2.7kg. An adjustable ball-bearing chuck, with a diameter range of D=0.5 to 8.0mm, secures the torsion bars in place. An open oil-filled damper reduces vibration amplitude. An exciter unit supports forced vibration experiments. All components are accurately placed in slots of the frame on the vibration system.
