【摘要】 铝型材挤压数值模拟过程中,由于工作带的存在,模具的一部分壁较薄,在进行有限元划分时网格细,结点和单元都较多,故花费计算时间也多。改善有限元的结点编号可以减少带宽,从而减少内存的消耗,减少计算时间,提高计算速度。本文用一种新的结点重编号算法对铝型材模具网格结点编号进行了优化,减少了有限元带宽。更多还原

【Abstract】 During the numerical simulation of aluminum profile extrusion process,die bearing makes some parts very thin and the grid of finite element fine.Renumbering node number of finite element makes the bandwidth reduced,the consumption of RAM decreased and computing speed increased.A renumbering algorithm has been presented which can optimize the node of die hence reduction of the bandwidth of FE in aluminum extrusion process.更多还原
