| Abstract: | The method of combining of the two basic tools-FEM -and Optimum method for practical problem-resolved in the design of products is discussed in the paper. Combined the practical examples, the selection and formation of optimum object function and state variable in design are also stated. It provides the scientific references in engineering design. The results indicate that feasible structural design can improve the security, it can also save the material .So the optimum design can improve the security and economic of design products for the two examples as follow. Combined the practical examples of optimum design, the method, concept of optimum design in CAE method is also described in this paper. |
