Abstract

According to the characteristics of loop-connection mechanism based on three quadrilateral elements and scissors elements, a construction method of Bricard-like mechanism based on scissors units and loop-connection mechanism is proposed. First of all, based on the analysis of the motion characteristics of the loop-connection mechanism of three quadrilateral units, a preliminary scheme of adding scissors units is put forward. Secondly, the folding and unfolding characteristics of scissors units are analyzed, and different requirements of bars length is put forward according to different characteristics. Finally, the three-dimensional models of Bricard-like mechanism based on scissors units and loop-connection mechanism is established, and its motion modes are analyzed. The proposed construction method can improve the folding ratio of the mechanism and provide some ideas for the design of large-scale folding mechanism.
