基于DEFORM软件，结合分模面圆角R，预锻与终锻模腔的长度、宽度、高度方向的百分比这4个因素，运用正交试验原理，研究了曲轴的塑性变形过程。从极差分析来看，对曲轴塑性变形载荷影响的大小顺序依次为：高度百分比＞长度百分比＞宽度百分比＞分模面圆角R。结果表明：在曲轴预锻塑性加工过程中，最大变形载荷为3.63×107 N，模腔分模面圆角R半径为8 mm、长度百分比为0.998、宽度百分比为0.98和高度百分比1.12为最优化设计；终锻时最大变形载荷为3.80×107 N，模腔分模面圆角R半径为8 mm、长度百分比为0.998、宽度百分比为0.95和高度百分比1.09为最优化设计。

The plastic forming process of crankshaft was simulated by software DEFORM and orthogonal test principle combined with four factors of mold parting surface rounded corners (R), the length percentage, width percentage and height percentage of cavity for pre-forging and final forging. Through the range analysis, the influence order of plastic deformation load on crankshaft is height percentage, length percentage, width ratio and R.The results show that in the plastic processing of crankshaft pre-forging, the maximum forming load is 3.63×107 N and the optimal design is mold parting surface rounded corners R of 8 mm, the length precentage of 0.998, width percentage of 0.98 and height percentage of 1.12, while in the final forging, the optimal design is mold parting surface rounded corners R of 8 mm, the length percentage of 0.998, width percentage of 0.95 and height percentage of 1.09.
