TM 150.02 Free and Damped Torsional Vibrations Show data sheet (pdf file) Print page
Technical Description

The experimental set includes three different torsion bars and two different mass discs. An oil damper makes it possible to reduce the amplitude. The components are straightforwardly and accurately placed in slots of the frame on the vibration system TM 150 or TM 155.


Learning Objectives / Experiments

- Natural frequency of torsional vibration
- Effect of torsional stiffness, rotating mass and damping



* Effect of rotating mass, torsional rigidity and

  damping factor on the behaviour of a rotary
