Abstract
Design and analysis of computer experiments (DACE) can solve the optimization design problem for stationary platen effectively. In this paper the method of uniform design is applied to obtain the design of computer experiments which is employed in the optimization design of the stationary platen. 3 factors (11 levels for each factor) are selected. The approximate Kriging model is built on the basis of the FEA results. 10 design points are selected randomly to verify the prediction ability of the Kriging model. The results show that the maximum of the relative error is 2.53% and the minimum is 0.63%. The approximate model built in this paper is practical in the optimization design of the stationary platen. The steps proposed in this paper are also suitable for the optimization design problems with complicated geometry or finite element model.
