摘　　要：通过对新型滚切式双边剪的空间剪切机构运动机理的研究和动力学分析,以实现纯滚动剪切为目标,对滚切式双边剪结构进行简化处理,得出以连杆机构为基础的简化模型,建立了连杆机构的动力学模型,编制了相应函数的仿真模块,运用Simulink进行动力学仿真;同时以某大型钢铁有限公司双边剪为依托,通过实验测出剪切过程中承力最大的重要杆件的受力值,对比理论公式和实际值的差值,发现结果相差较小,为该剪切机的机构设计、控制原理分析和实际使用提供依据。In order to achieve pure rolling and shearing,through a detailed analysis and study of the new rolling-cut bilateral shear on space shearing mechanism motion and kinetics,and simplifying the rolling-cut bilateral shear structure,a simplified model was obtained for linkage as well as its dynamics,and simulation module of corresponding functions were established.Simulink was applied to perform the kinetics simulation.Simultaneously relying on the bilateral shearer of a large steel company,the largest force value of the bar was obtained through experiments.Compared with differential between the theoretical formula and the actual value,the differential was small and this provided a basis for mechanism design of the shear and control principle analysis and actual use.
