并行计算是提高金属板料冲压成形数值模拟分析的计算速度和求解能力的有效途径。本文对板料成形数值模拟分析的并行计算的区域分解方法、并行求解及各 CPU之间的通讯以及显式解法处理接触时的并行计算公式等做了逐一介绍 ,最后给出了应用实例以说明得到的效果。
Parallel calculation is an effective way to improve the calculation speed and solving ability of numerical simulation of sheet metal stamping. In this paper, the regional decomposition method, the parallel solution and the communication between the CPUs of the sheet metal forming numerical simulation analysis and the communication between the CPUs as well as the explicit solution to deal with the parallel calculation formula of the contact are introduced one by one, and finally the application examples are given to illustrate Get the result.
