Planar mobility modes of 8-bar-jointed structures with a single degree of freedom
چکیده انگلیسی

A range of modes of mobility for spatial structures can be achieved by selecting the rotational features of the joints. Similar mechanical characteristics are observed in structures ranging from molecules to buildings. The local rotational manner in a solid with an internal spatial structure performs a key part in dictating the nature of structural deformability. In this paper, we propose a two-dimensional repetitive motion structure assembled with straight rigid bars connected by 8-bar pivot joints. By determining the rotational modes of the 8-bar joint with certain geometrical constraints, we introduce some telescopic transformations of the proposed structure producing both well-known and novel motions. In addition, we verify one of the deployable mechanisms by manufacturing it and testing activation by a single rotary operation.
