Experiment: 2DoF Forced Response Dynamics
Aim -
The aim of the experiment is to determine the natural frequencies of a beam mounted on two springs, which may be considered as a system with two degrees of freedom.
Experimental Setup -
The equipment to be used to carry out this experiment is shown in the diagram below.

Experimental Procedure -
For a range of frequencies (6 to 15 Hz with the step 1/2 Hz), measure using the CRO:
- A1, A2, A3 and F0- amplitudes of system response in points 1, 2, and 3, and amplitude of input force respectively; Plot frequency response function for three points. Determine the 2 natural frequencies.
Calculation -
Determine the 2 natural frequencies.
