Abstract
In this study a numerical method for optimum synthesis of spatial function generator four-bar linkages is presented. The key features of the method are: the embedding of the assembly criterion and of the transmission ratio in the penalty function; the non-derivative minimization procedure; the parametric variation of the first-guess mechanism. The effectiveness of the method is illustrated by means of examples of optimum design. In some examples articulated mechanisms, which can replace cam systems in automatic machinery, are synthesized.
Sommario
In questo studio si presenta un metodo per la sintesi ottimale di quadrilateri articolati spaziali generatori di funzione. Le principali caratteristiche del metodo proposto sono: l'inclusione del criterio di assemblabilità e dell'angolo di pressione nella funzione penalità; l'utilizzazione di un algoritmo di minimizzazione non derivativo; la variazione parametrica del meccanismo di primo tentativo. L'efficacia del metodo è messa in luce tramite una serie di esempi di progetto ottimale; in alcuni di essi sono stati sintetizzati dei quadrilateri spaziali in grado di sostituire i sistemi a camma spaziale nelle macchine automatiche.
