Abstract
Orthogonal design method is a sort of direct optimum method, by which the op- timal result may be obtained through simple computation and analysis. This method has gained increasingly extensive interest in scientific research, engineering design, end production management as well. The orthogonal table is the basic instrument for carrying out optimum design with orthogonal design method. It is a mathernatical table established On the basis Of the idea of isostatic distribution. As various levels may appear in any column, it makes a partial experiment contain levels of all factors furthermore. RII combina- tions of any two columns may appear , which makes any experiment between two fac- tors become overall experiment. Though the arrangement of the Orthogonal table is only for a partial experiment, nevertheless it may lead to understand the conditions of overall experiment. While making optimum design with orthogonal table. it may use the design vari- ables Of the mathmatical model for optimum design for the factors Of orthogonal table. and use the objective function f(X) for the experiment target. By means Of or— thogonal table for the arrangement of design plan, it is easy to determine an optimum design plan. This article recommends the basic principles Of using orthogonal design method to proceed with optimal design, and the prcress Of how to use orthogonal design method for the optimization of spring. From the theory and examples Of this article, it may clearly understand the su- periority Of applying orthogonal design method to conduct optimum design. The op— timum design can be obtained through simple computation. Jt is particularly suitable to conditions that the design variables are integer, or discrete variables
