摘要
利用曲线的几何特征 ,对Nongrashof机构的连杆曲线的分类问题进行了研究 ,提出了以曲线的结点、曲线的回转数、变曲点、曲率极大点等为基准的连杆曲线的自动分类法 。
Nongrashof Planar Four-link mechanisms generate complex coupler curves when the driving link oscillates in such a manner that the coupler and driven links belong to the different composition loops in going and returning respectively. In this paper, these curves are classified according to the numbers of the nodes, the inflection points, the maximum curvature points and the number of rotations of the curve.
