Abstract
In this paper, a new method to produce the functional continuum is proposed. The method is a topological optimization technique based on the function of a continuum and is composed of three steps. First, an initial mechanism model, which conforms to the given function, is determined using only some levers and supports. The mechanism model is changed to a framed structure as Rahmen model in the second step. The cross-section and length of members in the framed structure are optimized to maintain the original design requirement. In the final step, the framed structure is changed to the functional continuum using some well known shape optimization techniques. This method is applied to two problems of functional continuum. The first problem is to produce the continuum as orthogonal displacement transducer. The second problem is to produce the continuum having a bi-axial stress field under a uni-axial loading. From the results on these problem, it is obvious that the proposed method is very useful to produce the functional continuum.
