The study objective is to develop a method for the structural synthesis of closed kinematic chains of moving links of the first family (CKC) into the eleventh subfamily. The tasks are the following: based on the universal structural system (USS) of CKC, determine the composition of eight-bar CKCs of the eleventh subfamily of the fourth type and consider the procedure for applying the solutions obtained for the synthesis of structural circuits of these chains. Research methods: USS structural synthesis method, set theory and combinatorics, virtualization, identification and coding, graph theory. The novelty of the work: the features of USS use for determining the composition of eight-bar CKCs of the eleventh subfamily of the fourth type are considered, formation of structural schemes of these chains is discussed. Research results: combinations of kinematic pairs and links are found that make it possible to construct all possible structural schemes of eight-bar CKCs of the eleventh subfamily of the fourth type. A diagram of eight-bar CKCs of the eleventh subfamily of the fourth type is obtained.
