以高效率、高平稳性、结构简化为主要目标,对全铰链同轴双输出函数发生机构进行尺度综合.将该六杆机构视作由一套基础四杆机构和一套等价四杆机构并联而成.采用"分组综合"的策略,即先建立"按两个位置综合且瞬时传动比相等"为目标的基础四杆机构综合模型进行求解.再以该四杆机构为基础,运用"变杆长四杆机构"的等价原则,求得与基础四杆机构具有相似运动规律的等价四杆机构的尺寸参数.这样较好地解决了这一特殊的高阶运动参数尺度综合问题.实例综合结果表明该机构脉动值仅为6%.

In order to enhance the efficiency, stability and simplify the structure of the mechanism, the dimension synthesis of the full hinge coaxial two - output function generator is performed by using groupsynthesis scheme and regarding the six - bar mechanism as the parallel mechanism of a set of basic four - bar mechanism and a set of equivalent four- bar mechanism. Firstly, a basic four - bar mechanism synthetic model is established and solved based on two position synthesis and equal instantaneous transmission ratio. Then the dimensional parameters of an equivalent four - bar mechanism ( a five - bar loop) is solved by using equivalent principle of a variable link - length fourbar mechanism based on the basic four - bar mechanism. By this scheme, the dimensional synthesis of high order of motion parameter can be solved with good results, and the results show that the pulse data of the full hinge coaxial two - output function generator is only six percent.
