RETRACTED ARTICLE: A New Derivation Method of Contracted Graphs with Pentagonal Links Plus Other Links for Type Synthesis of Closed Mechanisms

In this paper, a derivation method is presented for the valid contracted graphs (CGs) with pentagonal links plus quaternary Q and ternary T using starting vertax arrays strings (SVASs) type synthesis of parallel mechanisms. First, some concepts on CGs, array (SVASs), basic (BCGs) are explained. Second, deriving CGs according to BCGs SVASs. According connections vertax, SVASs obtained. Then, principle permutation combination, all derived in link queue. Third, P, Q, closed mechanisms studied, many by
