定宽机主曲柄初始位置对模块有效行程的影响

Effect of initial position of SP main crank on die travel distance

系统地模拟了SP定宽机同步机构和侧压机构的运动规律,采用Powell优化理论,以模块最大有效行程为目标函数,以主曲柄初始角度和偏心距为变量进行优化分析,得到一组最优解。该结论为现场控制定宽机主曲柄的初始位置提供了理论依据。

The kinetic rules of synchronism mechanism and side mechanism are simulated systematically in this paper. By using Powell optimization theory, a set of optimum solutions has been obtained, in which the max die travel distance as the objective function and the initial angle of main crank and the eccentricity as the variables. The conclusion provides a theoretic base for in- dustrial control of the initial position of main crank.
