Structural design of planar mechanisms with dyads

In this paper, the structural synthesis of planar mechanisms with one, two and three dyads is studied. First a new classification of dyads is introduced and then a new way of constructing mechanisms is explained. The scheme provides a consistent coding scheme for planar mechanisms. The advantage of the classification of a system lies in its simplicity. The solution of the whole system can then be obtained by composing partial solutions. This approach will eliminate the need of storing complete mechanism information in a large database.
