具有给定行程速比系数的四杆机构的连杆点曲线综合

COUPLER-POINT-CURVE SYNTHESIS OF CRANK -ROCKER MECHANISM WITH THE GIVEN TIME RATIO

本文在取定曲柄固定铰连点位置和机架安装方位的前提下．解决了以下两方面的机构综合问题：一．综合曲柄摇杆机构．使机构具有给定的行程速比系数Ｋ．并且其连杆上某点的轨迹能通过五个给定的精确点；二．综合曲柄摇杆机构，使机构连杆上某点的轨迹能通过六个给定的精确点。

This paper solved the two following prolems of synthesizing a crank -rocker mechanism with given fixed pivot of crank and direction of fixed bar:firstly.synthesizing a mechanism with given time ratio.such that its coupler curve passes through five prescribed points;secondly,synthesixing a mechanism to guide a coupler point through six prescribed points.
