In the paper an attempt of a frequency analysis of a vibratory device model, performed by means of a new computational module implemented in the latest Autodesk lnventor Professional 2010 program version, has been presented. The results of an analytical solution and laboratory research of vibration of an one-sided constrained beam (carried out with the resonant method) have been presented. On the basis of findings, the estimation of an influence of the configurational parameters of the computational module, on the obtained eigenfrequencies and mode shapes coincidence, has been performed. A geometrie model of the assembly of a shape of vibratory device has been created. It consists of a base frame, four compression springs, a body with a top and a centrally situated inertial vibrator. Preparing the model of the device for the frequency analysis, the supportive calculations for the evaluation of the stiffness of springs and screws have been carried out. The first 11 modes and eigenfrequencies have been determined. Conclusions have been formulated.
