摘　　要：探讨了三曲柄对称式飞剪机剪切机构的运动轨迹和结构原理,采用ADMS软件进行飞剪机的结构设计及分析,得出各参数的相互关系,确定了最大剪切力的位置。该位置的合力计算值等参数及其相互关系,以及可根据不同剪切长度实时调整曲柄转速,为电机功率选择提供了依据。验证结果表明,理论计算准确,为构建新机构或改善现有飞剪机构的工作性能提供了有效的理论依据。For the movement track of flying shear with three symmetric cranks and its structural configuration, its principle was discussed with ADAMS. The mutual relations of each parameter can be derived, including the identification of the maximum shear stress positions, the calculation of its largest joint force and adjustment of the speed of the cranks according to different cutting length. This study provides the basis for choosing electric power. The outcome obtained will provide correct and effective theoretical method for developing new models and improving work performance of current flying shear.
