摘　　要：以公称压力2 600 kN、公称压力行程5 mm、最大行程次数8 000次/h平压平模切机双肘杆机构为研究背景,建立双肘杆机构动力学数学模型,得到平压平模切机双肘杆机构各个构件的水平惯性力、垂直惯性力,以及双肘杆机构等效到机身上总的水平、垂直惯性力和惯性力矩曲线。结果表明:水平方向惯性力振动幅值小于200 N,对模切机的影响很小;竖直方向上的惯性力随曲柄转角变化呈现先增大后减小的趋势,与理论分析相一致。Takes the nominal pressure 2 600 kN, the nominal pressure stroke 5 mm and the maximum stroke number 8 000 times per hour dual-elbow-bar mechanism of platendie-cutting machine as the research background. The dynamic mathematical model of dual-elbow-bar mechanismwas established, and curves of the horizontal inertia force and vertical inertia force of the dual-elbow-bar mechanism, as well as the total horizontal, vertical inertia force and inertia moment of the dual-elbow-bar mechanism to the fuselagewere obtained. The results show that the amplitude of the total horizontal inertia force is less than 200 N, and it has little influence on the die-cutting machine. The total vertical inertia force increases first and then decreases with the change of the crank angle. The amplitude of the total vertical inertial force obtained by the theoretical analysis is, and the amplitude obtained by the simulation analysis is.
