Free and Forced Vibration Apparatus- Engineering Lab Training Systems.
Technical Description
This experiment on vibration
is of a table-top design. All experimental set-ups are rapidly and
securely assembled on a double profile frame made of aluminium using
slot nuts and clamping levers. The vibrator 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 external computer-aided PC data acquisition and a
practice set for torsional vibrations are available as accessories.
