各类对称连杆曲线生成条件研究

Research on conditions of curve formation for various kinds of symmetric connecting rod

采用几何解析法研究曲柄摇杆机构特殊对称连杆曲线的产生条件,明确轨迹综合中极具价值的自切曲线、带单尖点和双尖点曲线,以及带近似直线段曲线所对应的连杆点位置,同时得到对称连杆曲线的形态种类及其分布规律。

The geometric analysis method has been adopted for studying the engendering condition of the curve of special symmetric connecting rod in crank rocker mechanism. The positions of connecting rod point that corresponding to the self-tangential curve, the curves with single tipped point and double tipped points and curve with approximate straight-line segments, which possess utmost values in track synthesis, had been made clear. The category of pattern of symmetric connecting rod curves and its regularity of distribution were obtained at the same time.
