The Torsional Vibration Trainer is designed to investigate torsion and torsional vibrations on shafts. Torsional vibration is achieved by constructing a steel bar with discs of different mass moment of inertia to it, then vibrations are induced in that system manually or using vibration inducer.

                                     
  • The unit consists of two steel bars, 4 discs with different masses, fixed chuck, oil damper, 4 angel rotation sensors, vibration inducer, signal unit and a control unit.
  • The unit is equipped with two bars of different thickness, 5mm and 6mm.
  • The trainer is composed of aluminum profile to attach on the desired elements with the desired spacing.
  • The oil damper is used to investigate the effect of damper on vibrations.
  • The torsion can be tested manually through manual vibration or automatically through a vibration inducer.
  • Vibration inducer is an electrically driven motor with four-bar link mechanism for inducing vibration-like motion.
  • The unit has four angel rotation sensors for the four different mass disks, which can display the vibration signal automatically through the software equipped.
  • The control unit allows controlling the vibration inducer and displays frequency.
  • The unit includes data acquisition system (PC interface) in the signal unit for transferring measured data to an external computer.
  • The unit is equipped with a CD containing interactive software to analyze the vibration signals and displays different values.
  • The unit is compact and table top mountable.
