Abstract: A technique was presented for dynamic modelling of a mechanical structure. It is required to establish an equivalent lumped parameter dynamical model for a given structure, then by means of undetermined parameter method, the dynamic parameters of the mechanical structure are calculated from measured response data. In order to raise the accuracy of identified parameters, an optimization procedure was used. This technique has been applied to modelling of a drill Z512-2, good result was obtained.
