为推导多杆机构的瞬停节传递特性 ,利用瞬停节的概念分析了 4杆机构和 6杆机构的自锁性能。根据 6杆机构存在多个瞬停节的现象 ,定义了瞬停节传递的概念 ,并证明了多杆机构瞬停节传递现象发生在新增杆组与组成瞬停节构件相连接的时候。因此利用瞬停节的传递可以进行具有稳定自锁功能的多杆机构设计 ;结合假肢的具体要求 ,还可以设计出具有可靠自锁功能的 6连杆假肢膝关节
In order to deduce the transfer characteristics of instantaneous stop of multi-bar mechanism, the self-locking performance of 4-bar mechanism and 6-bar mechanism was analyzed by using the concept of instant stop. According to the phenomenon that there are many momentary stops in 6-bar mechanism, the concept of momentary stop is defined and it is proved that the momentary stop of multi-bar mechanism occurs when the newly added bar is connected with the momentary stop. Therefore, the use of instantaneous stop section of the transfer can be carried out with a stable self-locking multi-bar mechanism design; combined with the specific requirements of prostheses, but also can be designed with reliable self-locking function 6-link prosthetic knee
