摘　　要：通过有限元模拟与实验验证对非轴对称复杂构件成形工艺进行优化。带有V形高筋的复杂形状构件作为关键承重部位被广泛应用。模拟了一次整体加载成形和两次局部加载成形的成形过程,研究了金属的流动特点。模拟结果显示,两次局部加载成形明显降低了成形载荷,提高了金属的充填成形能力,所需的成形载荷明显低于一次成形所需载荷。本文研究了金属成形时所需的成形载荷和速度流动场分布。实验结果表明两次局部加载成形明显降低了成形载荷,成形件满足尺寸精度与机械性能要求。The required forming loads and velocity flow filed during melal fiJrming process the text.
