平面两自由度铰链五杆机构的类型及判别

The Types of 5-bra Linkage with two-degree of Freedom and Their Differentiation

根据以机构极端位置建模导出的曲柄存在条件,应用机架变换法导出了两自由度铰链五杆机构(不论连架杆是否为主动件)的全部类型.给出了判断机构类型的简明结论.

According to the condition of crank existence, all types of 5-bar linkage with 2-degree of freedom are synthesized by linkage mould in extreme position. The concise conclusion for differentiating the types of 5-bar linkage is given with the method of frame inversion.
