dcterms:description
These days there is the main effort of car producers in the highest extent to decrease environmental load at car operation. One of the possibility represents reduction of the car weight. That is why there is still increasing portion of using strength materials and alloys based on the aluminium during last years. Processing of these specific materials reveal production problems which can be mostly eliminated by the proper pre-production phase. At this design part of the production technological processes take place predominant role numerical simulations of production process by FEM. For proper computation there is beside geometrical requirements on the stamping shape also necessary knowledge of the material deformation behavior and choice of the suitable computational model. For specific materials mentioned above are still developing new computational models with higher accuracy. In this paper is evaluated the computational model influence on the numerical simulation accuracy in the PAM-STAMP 2G environment at forming aluminium alloy EN AW 5754. For deformation analysis by FEM were used two anisotropy computational models marked like Hill 48 and Vegter. Numerical simulation results are evaluated based upon comparison of the deformation distribution on real stamping and measuring drawing force value. Deformation distribution on the real stamping is carried out by means of contact-less optical system ARGUS. 54 These days there is the main effort of car producers in the highest extent to decrease environmental load at car operation.
