چکیده
With the aim of revealing effects low temperature on vibration impact comminution performance wheat bran, dynamic bran at different temperatures was simulated by using LS-DYNA. According to collision relationship between grinding medium and a three-component numerical calculation model established. The essence analyzed, solution method based LS-DYNA proposed. On this basis, finite element obtained. By adjusting mechanical parameters in model, were analyzed. It is found that contact force, deformation energy increase with decrease temperature, which indicates low-temperature more advantageous than room comminution. However, when drops from - 40 ℃ 80 ℃, above index almost remain, indicats it economical apply range ~ 0 ℃. This research provided foundation for analysis, prediction optimization bran.
