摘　　要：通过引入固定、浮动坐标系和支撑函数法,揭示瞬时一维直线区域和投影得到瞬时区间套,进而提出推程、回程和整程区间套等概念,给出了求解平底方位线容许选择区域、凸轮基圆半径r0许用取值范围的基本原理,推导得到求解计算的一整套通用解析公式,得到解存在性和存在性态的系列判据,解决了作平面运动平底从动件盘形凸轮机构的第Ⅱ类机构综合问题。By using fixed/floating coordinate system and the support function method, the instantaneous 1-D linear area and interval sets were proposed. The rise motion, return motion and whole motion interval sets were put forward. The basic principles of solving the allowable selected area of the flat-faced line and the allowable value range of the cam basic radius were proposed. The analytic formulae were derived. Then the analytical criterion of the solution existence and its existing form were obtained. The class Ⅱ synthesis of disc cam mechanism with flat-faced follower in planar motion was resolved.
