The VI simulates the Fourier analyzer apparatus and it is possible to be used in the assisted research of the many other mechanical applications where it is necessary to know the vibration spectrum and how the constructive and functional parameters and the mouvements cases determine the major changes of the spectrum.
In the paper there were resolved the following problems: the theoretical and the experimental assisted research with data acquisition by using the proper theoretical and experimental Fourier VI; the optimization of the dynamic frequency spectrum with the virtual proper Fourier analyzer; the choice of the optimal movement case of the robots arm, after comparing between them the Fourier power spectrum.
The experimental Fourier analyzer contains the following modules: the module of the on-line command with many different characteristics of the velocities; the module of the data acquisition what assures the two channels of the acceleration acquisition between the motor of the shoulder and the end-effector; the mathematical module what determine the transfer function between the motor and the end-effector in the different movements and the Fourier transformation.
