A new approach to the design of high speed planar mechanisms is presented which makes it possible to synthesize a linkage to satisfy prescribed kinematic criteria while simultaneously minimizing each of its dynamic reactions. A nonlinear programming formulation is given which is capable of finding that linkage, among the theoretically infinite number of possible solutions associated with a number of specified precision points, which has optimal dynamic characteristics. The formulation is also extended to a non-precision point synthesis involving more specified design points than mechanism variables to make possible the minimization of maximum dynamic reactions while limiting the maximum structural error to a prescribed upper bound. The method is illustrated for both cases by application of the technique to the synthesis of a path generating linkage with coordinated input crank rotations.
