Some Remarks on Displacement Based Dynamic Measurements
In case of dynamic measurements under moving load when we are recording displacements instead of accelerations or velocities dominant values belong to static displacements. Performing discrete Fourier transforms static displacements due to moving load show as large amplitudes in very low frequencies. A general filtration rule that would eliminate the influence of recording the static displacement along with dynamic vibrations could not be found in all examples and a conclusion was drawn that in order to perform frequency domain analysis static displacements have to be eliminated on the signal level. Two examples have been devised in order to demonstrate the necessary procedures for determining the eigenfrequency of a beam structure from laser measured dynamic displacements.
