Force identification from noise-polluted vibration measurements

In the present paper an approach in the frequency-wavenumber domain able to determine a set of concentrated forces acting on a structure through response measurements is presented. The method allows the identification of both locations and intensities of the applied forces even when they are applied in points not amenable of measurements. The sensitivity of the solution to the noise in the measurements is studied. Experimental and simulated tests are performed on a onedimensional structure.
