摘要
对平面机构运动链的结构进行了分析,研究了闭式运动链的构件数、运动副数及闭链数三者的关系,同时研究了运动链结构的变化规律,提出了自由度K的闭式运动链的基本链型和两杆三副构件的两种不同结构,并指出在基本链型的基础上,运用两种不同结构的两杆三副构件,可以构造出复杂结构的闭式运动链。
After the structure of planar kinematic chain was analyzed,the relationships about the number of links ,pairs ,and loops in a planar kinematic chain train and its construction are also researched. The basic type of the K-DOF planar kinematic chain and two different structures called two-links -and- three-pairs are presented. By the basic type of planar kinematic chains and the two different structures ,the any complexes chains can be constructed.
