Abstract

This work presents a method based on Computer Aided Design or CAD for facilitating the synthesis of Revolute-Revolute (R-R) dyads with adjustable moving pivots. The CAD-based method presented in this work ensures that all prescribed rigid-body parameters used to synthesize the R-R dyad satisfy particular kinematic requirements of an R-R dyad. Through the application of this CAD method, five of the six general R-R dyad constraint equations are satisfied and therefore not essential for the synthesis of the R-R dyad. By reducing the number of dyad design constraints from six to one, the user can synthesize R-R links with adjustable moving pivots for multi-phase motion and path generation applications. The example included demonstrates the use of the CAD method in the synthesis of an RRSS path generator with adjustable moving pivots.
