Abstract Aimed at improving the robustness and reliability of optimal result of the foam-filled thin-walled structures’ crashworthiness, the uncertainties existed in the design variables were considered, thereby a robustness optimization method which was based on the experimental design method, Kriging metamodel technique, Monte Carlo method and method was applied into an optimization process of the foam-filled tapered thin-walled structure’s crashworthiness. The result showed that the structure’s crashworthiness was improved, and compared with the certainty optimal result the robust optimal result has higher robustness and reliability. Additionally, this example indicated the practicability of this method.
