Objectives of studying the discipline

The aim of the course is to research and computer design systems having a complex structure.

As a result of the study, the master student must be able to:

  • create computer 3D models of mechanical systems in the main CAD / CAE packages;
  • build geomechanical models, take into account the complex properties of soils and rocks;
  • be able to reduce the strength calculation of a complex system to the calculation of fragments of the environment, private nodes or individual parts;
  • use fictitious parameters for modeling the creep of homogeneous bodies and media using standard software;
  • build parametric models of machine parts;
  • solve problems and hydro- and gas dynamics, acoustics, heat transfer / heat resistance;
  • solve the problems of kinematics and the dynamics of complex mechanisms;
  • conduct functional and cost analysis of complex systems in order to optimize their structures.
