Synopsis:

The aim is to learn how to create the machine model, to gain knowledge of the dynamic properties of machines in context.

•Modeling of machines and their parts.

•Flexible machine mounting, vibroisolation, vibroabsorption.

•Mechanical characteristics of drives and loads. Basic tasks of machine aggregate dynamics.

•Influence of clutches and gears. Dynamics of electromechanical systems.

•Dynamics of drive systems. Dynamic models of flexible structures with drives.

•Transformation of state space model into modal and balanced form.

•Methods of model reduction with and without residues, joining of partial models.

•Experimental identification of models of flexible machine structures.

•Methods of identification of ERA, MOESP and N4SID.

•Dynamic models of mechanisms assembled by LRST.

•Interconnection of models of mechanisms and models of flexible drive chains.

•Kinematic calibration of machine mechanisms.
