Topology and parameter optimization of a foaming jig reinforcement structure by the response surface method
چکیده انگلیسی

A dilemma in the foaming of inner polyurethane (PU) pieces for household refrigerators is that of keeping the production costs down without adversely affecting the dimension precision. One way to do this is to reduce the electric power consumption spent running the polyurethane foaming line in which a number of heavy foaming jigs are continuously circulating, by optimally designing the reinforcement structure of the jig. In this paper, topology optimization and parameter optimization utilizing the response surface method (RSM) are applied for the optimum design of the jig reinforcement structure, in order to minimize the total jig weight while securing the dimension precision of the foamed urethane case. Both the reliability of the approximated response surfaces and the validity of the proposed optimization procedure are verified through illustrative optimization experiments. In addition, it is confirmed that the proposed procedure provides us with an optimum reinforcement structure which remarkably reduces the total jig weight.


► A topology and parameter optimization method by utilizing the response surface method is introduced.
► The total weight of the foaming jig was reduced by 19%, mostly by topology optimization.
► The design parameter dimensions were rapidly obtained by parameter optimization.
► The proposed method can be applied to various complicated engineering structures.
