natural frequency on the freely vibrating bending beam

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.
