采用有限元方法对曲轴锻造成形工艺过程进行数值模拟，主要分析不同的飞边槽结构对曲轴预锻成形中坯料的充填情况及成形栽荷的影响。根据模拟结果可知，在飞边槽桥部合理增设阻力沟或阻力墙，将对曲轴平衡块的充填性有很大程度的改善，并优化了毛坯尺寸。
採用有限元方法對麯軸鍛造成形工藝過程進行數值模擬，主要分析不同的飛邊槽結構對麯軸預鍛成形中坯料的充填情況及成形栽荷的影響。根據模擬結果可知，在飛邊槽橋部閤理增設阻力溝或阻力牆，將對麯軸平衡塊的充填性有很大程度的改善，併優化瞭毛坯呎吋。

By using FEM numercial simulation, the forging process of crankshaft is studied. The different structures of fash slot are mainly considered in the pre-forging process, in order to analyze the situation of the blank filling and the forging load. According to the results of numercial simulation, the structure of resistance ditch or resistance wall is reasonably added in the bridge of lash slot, which will greatly improve the filling of crankshaffs balance block, and finally optimize dimension of the blank.
