Abstract

A method for automatically altering the geometry of mechanical parts due to a change in design parameters is presented. The formulation for computing the effects of changes in design parameters of mechanical parts and mechanisms is based upon kinematic criteria adopted from mathematical formulations used in multibody dynamics analyses. The modelling method presented is based upon the representation of the geometry of a mechanical part using a combination of links and joints. Constraints describing the relation between two links are specified. A cut-joint method is used to transform mechanisms with closed loops into a tree structure graph. Variational displacements and orientation matrices are then derived with respect to design parameters. The formulation is used to compute new geometric design parameters after an alteration in the initial design. The formulation is demonstrated using a numerical example.
