The relative sensitivity concept, which is the ratio of stiffness to mass, is proposed when the inner plate of resin back door is divided into multiple sub-regions in this paper. The variables with certain threshold value are selected as research objects. Then DOE samples are obtained by using Optimal Latin Hypercube method, and Kriging model is established and its accuracy is verified. NSGA-II is used to solve the model, then Prato optimal solution set and best structure are obtained based on the target. The results showed that, the multi-objective optimization method based on Kriging model established in the paper is effective for improving the torsional stiffness of resin back door on vehicle.
