摘要
本文提出了曲柄摇杆机构的极位夹角不仅可以是锐角,而且可以是直角和钝角的新观点;给出了曲柄摇杆机构极位夹角的确切定义;导出了单侧摆动型曲柄摇杆机构极位夹角判别式。
In this paper,a new viewpoint that the extreme position angleof crank-rocker mechanism may be not only an actute angle but alsoa right or an obtuse one is put forward;The extreme positionangle of crank-rocker mechanism is exactly defined;And thediscriminant for extreme position angle of mono-side swing typecrank-rocker mechanism is deduced.
