摘要：
Lightweight design of mechanical parts plays an important role in improving equipment performance and reducing cost. To improve convergence, optimization efficiency for the parts lightweight design of traditional Kriging method, an adaptively dynamic Kriging model was proposed. The multiple correlation coefficient was utilized to achieve the goal of overall update of Kriging model, and the minimums of each objective from the Pareto solutions were utilized to search for the optimal characteristic point. Then the local update of Kriging model was achieved by the feasible solutions near the optimal characteristic point. Numerical test cases and a platen of FT(N)-2800 injection machine were given to demonstrate the effectiveness of the proposed method. © 2019, Editorial Department of CIMS. All right reserved.
