In the present, the application of computer simulation is increasing very fast. So far, it has been used relatively little for diverse reasons, such as high cost, demands on hardware, experienced staff, in some cases certain software deficiencies, etc. Today, however, it is no longer possible to work without these simulations since the requirements for the quality of manufactured components are steadily increasing. At Brno University of Technology two software program are mainly used: DEFORM 2D + 3D and the Czech FORMFEM program. The paper analyses the main reasons why simulation should be used and what experience and knowledge of simulation have so far been obtained. A practical example of the production of a canvas ring (i.e. a ring used in canvas covers) of sheet metal is given, inclusive of the simulation and a comparison with experimental test results, which have fully confirmed the simulation results.

Presentovaný příspěvek se zabývá problémy při počítačových simulacích a testuje dostupné software z FSI VUT v Brně. Jedná se o programy DEFORM 2D + 3D a FORMFEM.
