Features

* Demonstration of fundamental aspects of mechanical vibration₁
* Damping and resonance with forced vibrations₁
* Two different principles of exciting vibration

Sci-tech Free & Forced Vibration Apparatus Model MT 049 is an experimental unit based on the theory that vibrations are rapidly and securely assembled on a double profile frame made of aluminum using slot nuts and clamping levers. The oscillator consists of a beam mounted in ball bearings at one end; a helical spring is hung on the other end of the beam. The attachment of springs, the exciter and a damper to a perforated panel permits a wide range of different set-ups to be reproduced. Either an unbalance exciter or a displacement exciter generate vibrations; the frequency of the vibrations can be adjusted using the electronic control unit. The displacement exciter can be fitted directly to the base of the spring. The vibrations can be damped using the adjustable viscosity damper. To record vibration processes over time, a mechanical drum plotter is included.

The experiment also includes an amplitude contact with a TTL output, e.g. for triggering stroboscopes.

The measured values can be evaluated with the software for data acquisition(optional).

A practice set for torsional vibrations is available as accessories.
