ACTIVE DESIGN OF A FLEXIBLE SPACE MECHANISM WITH OPTIMAL CHARACTERISTICS

A new method for the optimum synthesis of flexible mechanisms is prese nted in this paper. The concept of characteristic parameters is propos ed firstly and applied into the design process of a flexible mechanism , which leads the design to an active way. The difficulties of selecti ng an initial value and searching a global optimal solution in optimis ation are overcome through a fore process of the dynamic characteristi c analysis of flexible mechanism in spectrogram forms. The computation time is reduced greatly in this active design procedure. As an exampl e, the design of a flexible RSS'R space mechanism with optimal dynamic characters is obtained successfully by this method. The encouraging r esult is, through comparison, found to be superior to that obtained by general methods.
