Simulation analysis of double normal pressure peaks

Journal Article


Abstract


  • In some flat rolling procedure, the normal pressure in the contact zone shows double peaks. According to the rolling conditions in the reference paper, the flat rolling procedure is simulated by dynamic explicit elasto-plastic finite element method. The results from the simulations are in good agreement with those from the experiments. The normal pressure obtained from simulation shows double peaks. Through the analysis of the bite stage and the whipping stage in the rolling procedure, the factor of the double normal pressure peaks is obtained. The elastic zone after contact zone of the strip is the main factor and it will bring the double normal pressure peaks together with contact friction.
