Then, by iSIGHT, experiment designs are redesigned of 40 kinds of different ""V-type"" folded core. Based on the above, a surrogate models are built for thermal conductibility performance of sandwich panel with ""V-type"" folded core in this paper, and they can be optimized by multi-subject. The numerical simulation function and optimization design method in condition of lightest weight are shown in this paper.
