We present a shape representation and algorithms for the simulation and shape synthesis of kinematic higher pairs. The shape of a kinematic member is represented as an arrangement of small contiguous nondirected circles, which we call 'molecules'. Given the shapes of the two members, a valid initial configuration, and the motion of one of the members (known as the driver), the motion of the other member (known as the driven) is determined. This simulation is based upon finding the points of contact between the member shapes. Contact is defined by interference of the molecules. As output, the simulation produces the functional relationship between the members and a record of the molecules of each member shape that came into contact during the process. Two procedures for shape synthesis are described. Given the shape of one member and the functional kinematic relationship between the member pair, the first procedure generates the shape of the second member from a blank of material. The second procedure modifies the shapes of two interacting members in order to change their contact characteristics during a kinematic interaction. Several examples from an implementation are provided. [ABSTRACT FROM AUTHOR] |
