中文摘要：

通过对新型多自由度复合连杆滚动剪切机构的原理分析,建立了连杆剪切机构的位置环方程组,修正了导向杆与机架铰接位置的确定方法。以某大型钢厂的全液压滚切剪机开发为依托,对新型剪切机构的滚切运动轨迹进行了模拟仿真,模拟结果为电气液压伺服控制系统实现速度及位移的控制提供了精确数据,生产现场高质量的钢板剪切断面证实了合理的机构杆件尺寸是降低刀弧水平位移量、提高剪刃重叠量均匀度、实现高精度剪切的重要手段。

英文摘要：

Through analyzing the theory of a new multi--degree --freedom composite linkage rod rolling shear mechanism, position loop equations of the link shear mechanism were established, and the guide rod and frame hinged position determination method was corrected. Based on a large steel mill hydraulic rolling shear machine development, the new shear movement trajectories were simulated. The precise simulation data for the electric hydraulic servo control system provides a guarantee to re- alize the speed and position control precision. The production of high quality steel plate shear section confirmes the reasonable institutions stem size can reduce knife arc horizontal displacement,improve the evenness of shear blade overlao, realize high precision cutting.
