Abstract
This paper describes the robust design method base on CAE. In initial design stage of mechanical design, the advantage of the conventional method, Monte-Carlo method, Taguchi Method etc, is limited. Because it is need to define the noise factors as a known quantity. In this paper, novel approach which can be applied to initial design stage is proposed. The basic idea is that the noise factor is not design parameter (ex, machine component shape, stiffness of weld), but characteristic of system (ex, the interference of sound, particle velocity). In this paper, the basic idea is applied to simple FE model.
