On Design Technique of Functional Continuum using Combined Simple Models.

Abstract

In this paper, the design method of the functional continuum by combining the fundamental simple mechanism models is proposed. First, the formula to calculate the whole displacement ratio of output to input is deduced from the mechanical analysis of the two simple functional continuum which are combined. By using this formula, the design condition amplifying displacement is obtained, and applied to the device design which amplifies the displacement into the same direction. In this design, the optimum structure, which has the maximum displacement ratio, is obtained by using the displacement ratio and stiffness coefficient that are analyzed by the finite element method of each device to this formula. As the results, it is obvious that the proposed method is useful for the design of combining the functional continuum.
