平面四杆机构极位夹角的取值范围

Range of Crank Angle Between Extreme Positions for Planar Four-bar Linkage

对平面四杆机构极位夹角的定义作了较确切的表述,并推导出了曲柄摇杆机构、曲柄滑块机构和摆动导杆机构极位夹角的取值范围。

This paper gives a precise definition about crank angle between extreme positions for planar four-bar linkage and deduces the range of crank angle between extreme positions of crank-rocker mechanism , slider-crank mechanism and crank shaper mechanism.
