摘要

针对国内外现有的板材剪切机在工作时容易出现缺陷和难以控制的问题,提出一种新型的单液压缸驱动液压滚切剪。以实现纯滚动剪切为目标,通过简化杆件,获得PR-11RⅢ级杆组的复合连杆机构简化模型,利用杆组分解建模的方法建立连杆机构各级杆组的动力学模型,并编制相应函数的仿真模块。以某机械有限公司2 000 mm单液压缸驱动的液压滚切式板材剪切机为依托,运用Matlab/Simulink软件对其进行动力学模拟仿真。仿真结果得出的关键铰接点的动力学曲线和参数为该剪切机的机构设计、控制原理分析和实际应用提供了重要的依据,同时也证实了其动力学理论分析的正确性。

Abstract

A new rolling shear mechanism which is driven by one horizontally positioned hydraulic cylinder is put forward through analyzing the present shear mechanism at home and abroad. In order to achieve pure rolling and shearing,the simplify model of PR-11RⅢ-level composite rod linkage mechanism is obtained.Besides,by using the method of assur-group decomposition modeling,the dynamics model of every assur-group and corresponding simulation model are established,and the simulation module of the corresponding function is compiled. Finally,depending on the development project on extensive popularization of 2 000 mm rolling shear mechanism driven by one hydraulic cylinder of a machinery company,the dynamics simulation is conducted by using the Matlab/Simulink. The important basis for mechanism design of the rolling shear and control principle analysis and actual use is provided by the dynamics curve and parameter of key hinge joint botained from the simulation result,the correctness of the dynamic analysis is verified.
