Universal Vibration System
Technical Description:
The trainer covers a wide range of topics in mechanical vibration technology. It is mounted on a sturdy, low-vibration frame which is installed on a laboratory trolley with braked wheels. Quick fastening elements for the formed grooves for quick and accurate experimental set-up. Forced vibration is generated with an electrical motor-driven imbalance exciter. The exciter frequency can be set precisely on a control unit with digital display. An oil damper is used for vibration abatement. A bar-type oscillator that can be adjusted with weights is included for absorber experiments. A mechanical drum and a polar diagram recorder record the vibration. The single parts are stored in the protective storage compartments of the laboratory trolley.
