摘　　要：引据几何学Apollonius定理,发现在已知摇杆长度、摆角和缸-杆伸缩比条件下,传动缸固定铰链中心点的可落居区域——解集为简单规则的几何图形——"圆",提出了"辅助圆"的新概念;据此给出了Ⅰ型、O型和Ⅱ型机构的概念及其拓扑结构特征;讨论了缸-杆的初始长度、机架长度、初始安装角随传动缸固定铰链中心点位置变化而变化的规律,给出了摆动传动缸机构通常条件下简洁、明快的图解设计方法。Based on Apollonius theorem in geometry,under the condition that the length and the swing angle of rocker,and cylinder-rocker extension ratio are given,the selection area of the fixed hinge center-point was found,whose solution set is a simple and regular geometric graph-＂circle＂,proposing a new concept ＂auxiliary circle＂.On the above basis,the concepts of type Ⅰ,O and Ⅱ mechanisms and their topological structure features were given;the change rules of cylinder-rocker＇s initial length,frame length and initial installing angle vary with the change of fixed hinge center-point was discussed.Finally,a simple and concise illustration design method of swing cylinder under normal condition was given.
