EFFICIENT DIMENSIONING OF MECHANISMS BY INTEGRATION OF PRECISION-POINT-SYNTHESIS WITH GENERAL NONLINEAR OPTIMIZATION

The kinematic synthesis of linkage-mechanisms needs repeated and inter locking steps of dimensioning, kinematic analysis, evaluation and opti mization. Serving this purpose, the program-system MOSYS has been deve loped at the ''Institut fur Getriebetechnik'' of the University of Han nover. It enables free composition of ''modules'' to build up adapted programs. A substantial element of MOSYS lies in the coupling of the c lassical precision-point-synthesis with non-linear optimization method s. This especially in a way that the accuracy positions as input of th e internal precision-point-synthesis themselves are treated as free op timization parameters. Thus one obtains excellent solutions in a much more effective way and without any restriction of the field of solutio ns than by a stand-alone-optimization on the base of directly using on ly linkage dimensions as such parameters. The principle, the structure , and the mode of operation of MOSYS will be explained and exemplified .
