分析了回转式飞剪机上刀轴在剪切过程中的受力状况，分别利用弯扭合成强度计算方法和安全系数法校核了改进设计的回转式飞剪机上刀轴疲劳强度和静强度。理论计算结果表明，上刀轴危险截面的弯曲应力均小于刀轴材质的许用弯曲应力，并具有足够的静强度安全系数。通过实际生产的检验，证明了改进设计的飞剪机能够满足生产线的使用要求。
分析瞭迴轉式飛剪機上刀軸在剪切過程中的受力狀況，分彆利用彎扭閤成彊度計算方法和安全繫數法校覈瞭改進設計的迴轉式飛剪機上刀軸疲勞彊度和靜彊度。理論計算結果錶明，上刀軸危險截麵的彎麯應力均小于刀軸材質的許用彎麯應力，併具有足夠的靜彊度安全繫數。通過實際生產的檢驗，證明瞭改進設計的飛剪機能夠滿足生產線的使用要求。

Stress analysis of rotary flying shear shaft during the shearing process was performed in this pa-per. Fatigue strength and static strength of the improved shaft was checked by respectively using bending-tor-sion composition calculation and safety factor method. The theoretical calculation results showed that the shear shaft bending stress on the dangerous sections is less than the allowable bending stress of the cutter shaft mate-rial, and the shaft had enough fatigue strength and static strength. The actual production proved that the im-proved design flying shear satisfied the requirements of production line.
