Analysis of elements network influence upon simulation results in the Dynaform 5.2 software

Abstract

The contribution concerns creation of elements network which is necessary at flat forming simulation and the analysis of meshing infuence upon simulation results. Meshing is an important process carried out before simulation, which affects final result. This process is analysed in the contribution, individual steps leading to aim are described. The possibilities of meshing in Dynaform 5.2 software evolved by American company Engineering Technology Associates, Inc. (ETA) are described. In contribution the meshing analyses are carried out on blank model determined by maximum shear stress trajectories method which is optimal for drawing of one of the representatives of intricate shape stampings from thin deep-drawing sheet-metal DC04 – left cover of ventilator for truck Tatra 815.
