平面低副四杆机构极位夹角及行程速比系数分析

Analysis of limited position angle and the travel velocity-ratio coefficient for plane lower pair mechanism

通过对平面低副四杆机构极位夹角传统定义的分析,根据机构中各杆长的变化,对极位夹角的定义进行了扩展,在此基础上对行程速比系数的取值范围进行了合理的选择。

In this paper,based on the analysis on the tradition definition of the limited position angle of the plane lower pair mechanism and according to the length change of mechanism,the definition of limited position angle is expanded.On the basis,how to choose the limited of travel velocity-ratio coefficient reasonably is decided.
