| 摘 要： | 空间两轴垂直交叉的RSSR曲柄摇杆机构和RSSP曲柄滑块机构,是空间连杆机构中应用最广泛的四连杆机构。本文运用拓扑变换原理,对RSSR和RSSP这两种机构,按极限位置和行程速比的综合进行了分析研究。导出了其尺寸参数的计算公式,并提出了电子计算机辅助设计和绘图的程序框图,以定量的方法分析设计机构的可动性,这一方法具有图文并茂,形数结合,结论准确,容易理解等特点,编成软件后,使用极其方便。因而,是一种较为理想的方法。可供有条件的单位应用。

| Abstract: | The RSSR crank-rocker mechanism with two shafts crossed at right angles and the RSSR slider-crank mechanism are most widely used four-bar spatial linkages. On the basis of topologic transformation principle, the synthetic approach of these two kinds of mechanisms by prescribed extreme positions and coefficients of travel speed variation has been studied. The dimmension design equations and the program charts of computer aided design (CAD) and computer graphics (CG) are presented. The mobility of mechanisms is analysed and designed quantitatively. The synthetic approach is an ideal method. |
