摘要
运用复数-极坐标矢量法[1](以下简称复矢量法)建立了冲床中的连杆机构动态分析力学模型。通过对机构运动全 过程的分析,结合动力学普遍方程,给出了冲头加速度及冲力的变化规律。为合理设计冲床提高冲击效率提供了理论基础。
The mechanical model of the dynamic analysis of conecting rod mechanism in the punch is estalblished by complex vector method. By analysis of the whole process of mechanism motion general equation of the dynamics, the change law of the acceleration and impulsive force of the punch pin isg iven out. The basic theory is provided for reasonably designing the punch and raising the impact efficiency.
