On the application of CAD technology for the synthesis of spatial revoluterevolute dyads
This work presents a method based on Computer Aided Design or CAD for facilitating the synthesis of RevoluteRevolute (RR) dyads with adjustable moving pivots. The CAD-based method presented in this work ensures that all prescribed rigid-body parameters used to synthesize the RR dyad satisfy particular kinematic requirements of an RR dyad. Through the application of this CAD method, five of the six general RR dyad constraint equations are satisfied and therefore not essential for the synthesis of the RR dyad. By reducing the number of dyad design constraints from six to one, the user can synthesize RR 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.
