Free vibrations in a bending beam (SE 110.58)

Free vibrations in a bending beam (SE 110.58)

natural frequency on the freely vibrating bending beam

CodeSE110.58

Description:

  • 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 112mounting frame.
  • The natural frequency is affected by the clamping 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 signal can be displayed on an interlaboratory oscilloscope.
