DYNAMIC DESIGN
OF VARIABLE
SPEED PLANAR
LINKAGES*
Abstract: A method for improving dynamic characteristics of planar linkages by actively varying the speed function of the input link is presented. Design criteria and constraints for the dynamic design of variable speed planar linkages are developed. Both analytical and optimization approaches for deter-mining suitable input speed functions to minimize the driving torque, the shaking moment, or both simultaneously of planar linkages, subject to various design requirements and constraints, are derived. Finally, some examples are given to illustrate the design procedure and to verify its feasibility.
