TM 150 Universal Vibration System Show data sheet (pdf file) Print page
Technical Description

The instructional system covers a wide range of topics in mechanical vibration technology. It is mounted on a sturdy, low-vibration aluminum sectional frame which is installed on a rolling 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 unbalance 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. The external computer-aided PC data acquisition (TM 150.20) and a practice set for torsional vibrations (TM 150.02) are available as accessories.
