具有5点接触直线的铰链四杆机构的解析综合

给出了在一种特殊位形情况下综合连杆曲线具有5点接触直线(Burmester点)的铰链四杆机构的解析方法.用该方法综合铰链四杆机构可预先给定欲逼近直线上的点、直线方向以及一个固定铰链的位置.推导出了综合公式并给出了综合示例,证明了综合公式的正确性.

Analytical Synthesis of Four-bar Linkage in the Special Configuration with Coupler Curve Having a 5-Point Contact with Its Tangent

A analytical synthesis method of four-bar linkage in the special configtiration, in which the coupler curve has a five-point contact with its tangent (Burmesters point), is presented. With this method, the point which is on the expecting straight-line, the direction of the line and one frame point, can be given beforehand. Some synthesizing formulae are derived and three synthesizing examples are given. The results have proved that the formulae are correct.
