Abstract:

A unified design methodology has been developed for the creative design of mechanisms. This is based on an abstract representation of the kinematic structure of mechanisms, which we have called the stratified representation of mechanisms. This transforms the basic structure of a mechanism into an essentially unique spanning tree with a minimum number of edges, each associated with a fundamental loop. In this fashion hundreds of thousands of mechanisms have been generated automatically, thus providing a creative design tool of extraordinary power and efficiency. The same basic approach has been developed for the automatic determination of favorable mechanism dimensions by means of algorithms for the determination of the rotatability of the rotatability and assembility of the links, while eliminating crossing links. Keywords Artificial intelligence Polynomials Algorithms Computer aided design.
