Synopsis:

Subject is oriented on mathematical modelling of mechanic and hydrodynamic systems and their computer simulation. Subject deals with systems with one or more degrees of freedom with consideration of passive resistances, power losses and conditional bonds. It presents different methods of parameters identification in dynamic system. Work in computer laboratory is aimed on solving of mathematical model with application of computer programs and its experimental verification on real mechanical models.
