SE 110.58 Free vibrations in a bending beam
An oscillator, which is left alone after a single excitation, performs free vibrations. The frequency of the free vibration is the natural frequency of the oscillator.
In SE 110.58, a bending beam is used as the system’s oscillator. The bending beam can be used vertically standing or hanging and in the horizontal position in the SE 112 mounting frame.
The natural frequency is affected by the clamp length and the sliding weights. The bending beam is deflected by hand and performs free, damped vibrations. The resulting amplitudes are measured via strain gauges and a measuring amplifier. The measured values are transmitted directly to a PC via USB, where they can be displayed and the results of the experiments analysed graphically using the software included.
